The engine lubrication system delivers clean oil at the proper temperature and pressure to all engine parts. The oil is pumped from the sump through an oil filter and feeds the main bearings and oil pressure gauge before passing through the crankshaft to the connecting rod bearings. Cylinder walls and piston pins are lubricated by oil flung off the crankshaft, with excess scraped off by piston rings. Camshaft bearings and timing components also receive oil bleeds, and excess oil drains back to the sump to disperse heat to the air.

Petrol engine vs diesel engine
Diesel engines differ from petrol/gasoline engines in that diesel engines ignite fuel via compression rather than with a spark plug. Diesel engines have higher compression ratios than petrol engines, ranging from 14:1 to 25:1. This makes diesel engines more efficient but also more expensive than petrol engines. While diesel engines have advantages like better fuel efficiency and reliability, they also have disadvantages like being noisier, producing more emissions, and being harder to start in cold weather. Both engine types are commonly used in vehicles, though diesel sees more use in larger transport like trucks and buses.
Fuel injectors
Fuel injectors deliver fuel directly into an engine's combustion chamber or intake port. They require precise nozzle design to properly atomize fuel for efficient mixing and combustion. Common nozzle types include single-hole, multi-hole, and pintle nozzles. Modern electronic fuel injection systems use either an electronic unit injector (EUI) or hydraulic electronic unit injector (HEUI) to precisely control fuel injection timing and quantity electronically for improved performance and emissions.

Brayton cycle
This Presentation was prepared for Brayton Cycle. This is very important in the study of THermodynamics.
Brayton cycle
George Brayton designed the first continuous combustion engine, known as the Brayton engine, in the 1860s. The Brayton engine introduced the Brayton cycle of continuous combustion that became the basis for gas turbine development. A Brayton-type engine consists of an air compressor, mixing chamber, and expander. The Brayton cycle uses four thermodynamic processes - two constant pressure and two reversible adiabatic processes - and is now used in gas turbines where compression and expansion occur via rotating machinery.
Brayton cycle
The open gas-turbine cycle works as follows:
1. Air is compressed in a compressor, increasing its pressure and temperature.
2. The high-pressure air enters a combustion chamber where fuel is burned at constant pressure.
3. The high-temperature gas expands in a turbine, producing work and reducing to ambient pressure.
The Brayton cycle models the gas-turbine cycle with constant-pressure heat addition and rejection processes. Actual cycles have irreversibilities from non-isentropic compression/expansion and pressure drops. Efficiency can be improved with regeneration, intercooling, reheating, and multistage designs.

Engine lubrication basics
Engine lubrication begins with oil pulled from the sump through a filter, then distributed throughout the engine via passageways to components like bearings and pistons. Lubricants contain additives like detergents that suspend harmful deposits in the oil to prevent damage. A multi-grade oil uses viscosity index improvers that allow it to flow easily at cold temperatures but maintain thickness at higher engine temperatures. Regular maintenance like oil changes is necessary to prevent additive depletion and lubrication breakdown from contamination, overheating, or long drain intervals.

The role of lubrication in an automobile : Purpose and practice. It is a short presentation on the topic, trying to cover some aspects of automobile lubrication.
Lubrication System of tractor
The document discusses lubrication systems for tractor engines. It describes three main types of systems: 1) Splash systems which rely on oil splashing from the crankshaft to lubricate parts. They are used on single cylinder engines but do not provide uniform lubrication. 2) Force feed systems which use an oil pump to pressurize and directly feed oil to parts through drilled passages to ensure adequate lubrication. 3) Combination systems which use an oil pump to feed critical parts while relying on splashing to lubricate other parts, providing both direct lubrication and splash lubrication.
LUBRICATING AND COOLING SYSTEM
The document describes different lubricating and cooling systems for engines. It discusses six types of lubricating systems: petroil, splash, pressure, wet sump, dry sump, and combination. Splash systems splash oil onto moving parts from a pan, while pressure systems precisely pump oil to bearings. Combination systems use both splash and pressure. The document also covers air cooling, which uses fins, and water cooling, which circulates coolant through jackets.
L -4 Lubrication system.pptx
The lubrication system reduces friction between moving engine parts to prevent wear, heat generation, and power loss. Lubrication oil forms a thin film between surfaces to minimize direct contact and noise. It also has cooling, sealing, and cleaning effects. Common lubrication systems include petro-oil mixing, splash lubrication using scoops, and forced feed/pressure lubrication using pumps to directly supply crankshafts, rods, and other parts. Proper lubricant selection and routine maintenance like oil changes are needed to keep the system functioning optimally.
Chap21
The document discusses engine lubrication systems and oil pumps. It explains how oil pumps work to circulate engine oil through lubrication passages to components like main bearings, cam bearings, and valve train parts. It describes the factors that influence oil pressure, like oil viscosity and pump capacity. It also covers checking oil pumps for wear and setting maximum pressure with relief valves.
Jet Propulsion: Oil and Lubrication Continued
Turbine engine lubrication systems have three sub-systems: the pressure system supplies clean oil at the proper pressure and temperature to bearings and gears. The scavenge system picks up used oil and returns it to the tank to be recirculated. The breather/vent system removes contaminated air from bearing housings through a de-oiler before blowing it overboard.
Halderman ch023 lecture
The document discusses lubrication system operation and diagnosis. It explains that the purpose of an engine's lubrication system is to supply oil to all moving parts to prevent wear, help cool the engine, and perform other functions. It describes how lubrication works through hydrodynamic lubrication principles. It also discusses how the oil pump, different types of oil pumps, and factors like viscosity and leaks can affect oil pressure.
MEC258A-IC Engines-Lubrication System in IC Engine.pptx
The document discusses lubrication systems in internal combustion engines. It defines lubrication as applying oil or grease to minimize friction. There are three types of lubricants: solid, semi-solid, and liquid. Lubrication systems include mist, wet sump, and dry sump. A wet sump system uses an oil pump to circulate oil through the engine via splash, pressure, or a combination. A dry sump system stores oil externally and uses scavenge pumps to circulate it. Proper lubrication reduces friction, heat, noise and corrosion in engines.
At11-Lubrication System.pptx
This document provides information on lubrication systems for automotive engines. It discusses the purposes of lubrication which include reducing friction and wear, providing cooling and cleaning, and cushioning shock. It also describes the key components of lubrication systems such as oil pumps, filters, coolers, and pressure indicators. Different types of lubrication systems are covered, including mist, wet sump, and dry sump systems. The document also examines various pump designs including gear, rotor, vane, plunger and crescent types. It provides details on cartridge and centrifugal oil filters. Finally, it discusses a specific lubrication system for a Tata 713tc engine.
Lubrication system.pptx
This document summarizes different types of lubrication systems used in engines. It defines lubrication as applying a substance like oil to minimize friction between moving parts. The main types discussed are mist/petrol, wet sump, and dry sump systems. Wet sump systems use a sump at the crankcase and either splash or pressure pumps to circulate oil. Dry sump systems store extra oil outside the engine and use scavenging pumps. Lubrication reduces wear, friction, and heat between engine parts like the cylinder, piston rings, crankshaft, and camshaft. While lubrication improves engine performance and efficiency, some systems add complexity, cost, and can cause smoke from oil burning.
ICE_Handout(5) for CI fuel injection.pdf
FUEL INJECTION SYSTEM FOR CI ENGINES
The function of a fuel injection system is to meter the appropriate quantity of fuel for the given
engine speed and load to each cylinder, each cycle, and inject that fuel at the appropriate time in the
cycle at the desired rate with the spray configuration required for the particular combustion
chamber employed. It is important that injection begin and end cleanly, and avoid any secondary
injections. To accomplish this function, fuel is usually drawn from the fuel tank by a supply pump,
and forced through a filter to the injection pump. The injection pump sends fuel under pressure to
the nozzle pipes which carry fuel to the injector nozzles located in each cylinder head. Excess fuel
goes back to the fuel tank. CI engines are operated unthrottled, with engine speed and power
controlled by the amount of fuel injected during each cycle. This allows for high volumetric
efficiency at all speeds, with the intake system designed for very little flow restriction of the
incoming air.
FUNCTIONAL REQUIREMENTS OF AN INJECTION SYSTEM
For a proper running and good performance of the engine, the following requirements must be met
by the injection system:
• Accurate metering of the fuel injected per cycle. Metering errors may cause drastic variation
from the desired output. The quantity of the fuel metered should vary to meet changing speed
and load requirements of the engine.
• Correct timing of the injection of the fuel in the cycle so that maximum power is obtained.
• Proper control of rate of injection so that the desired heat-release pattern is achieved during
combustion.
• Proper atomization of fuel into very fine droplets.
• Proper spray pattern to ensure rapid mixing of fuel and air.
• Uniform distribution of fuel droplets throughout the combustion chamber
• To supply equal quantities of metered fuel to all cylinders in case of multi-cylinder engines.
• No lag during beginning and end of injection i.e., to eliminate dribbling of fuel droplets into the
cylinder.
TYPES OF INJECTION SYSTEMS
There are basically two types of injection systems: Air injection system and solid injection system.
Air Injection System: In this system, fuel is forced into the cylinder by means of compressed air.
This system is little used nowadays, because it requires a bulky multi-stage air compressor. This
causes an increase in engine weight and reduces the brake power output further. One advantage that
is claimed for the air injection system is good mixing of fuel with the air resulting in higher mean
effective pressure. Another advantage is its ability to utilize fuels of high viscosity which are less
expensive than those used by the engines with solid injection systems. These advantages are off-set
by the requirement of a multistage compressor thereby making the air-injection system obsolete.
Solid Injection System: In this system the liquid fuel is injected directly in.
Unit Injector System: In this syst

Lubrication system
- 1. Lubrication system The engine lubrication system is designed to deliver clean oil at the correct temperature and pressure to every part of the engine. The oil is sucked out the sump into the pump, being the heart of the system, than forced through an oil filter and pressure feeded to the main bearings and to the oil pressure gauge. From the main bearings, the oil passes through feed-holes into drilled passages in the crankshaft and on to the big-end bearings of the connecting rod. The cylinder walls and piston-pin bearings are lubricated by oil fling dispersed by the rotating crankshaft. The excess being scraped off by the lower ring in the piston. A bleed or tributary from the main supply passage feeds each camshaft bearing. Another bleed supplies the timing chain or gears on the camshaft drive. The excess oil then drains back to the sump, where the heat is dispersed to the surrounding air.
