Thermal ii (ppt on valve timing diagram for four stroke si engine)
This document discusses the valve timing diagram of a four-stroke spark ignition engine. It begins by describing the main components of an S.I. engine and the four strokes of its cycle. It then explains that the valve timing diagram shows the angular opening and closing of the intake and exhaust valves throughout the cycle. Theoretical and actual valve timing diagrams are compared, with the actual diagram accounting for mechanical factors that cause the valves to open and close earlier than theoretically ideal times. Intake and exhaust valve timing are then described in detail for both low and high-speed engines.

The document summarizes the main internal combustion engine parts. It describes the cylinder block, cylinder, piston, combustion chamber, inlet and exhaust manifolds, valves, spark plug, connecting rod, crankshaft, piston rings, gudgeon pin, camshaft, cams, flywheel, carburetor, fuel pump, and fuel injector. It explains the purpose and function of each part in 1-3 sentences.

Valve timing diagram of four stroke diesel engine
The document discusses the valve timing diagram of a four-stroke diesel engine. It explains that the inlet valve opens a few degrees before top dead center to allow enough time for the valve to lift off its seat and allow more air into the cylinder. It also notes that this timing improves fuel evaporation and mixing. Additionally, it states that the exhaust valve remains open a few degrees after bottom dead center to allow for maximum expansion of the combustion gases and reduce the work required by the piston to expel the exhaust.

4 strok petrol engine
The 4-stroke engine cycle consists of the intake stroke, compression stroke, power/combustion stroke, and exhaust stroke within one revolution of the crankshaft. During the intake stroke, the intake valve opens and the piston travels down to allow an air-fuel mixture into the cylinder. In the compression stroke, both valves are closed and the piston compresses the mixture. The spark plug then ignites the compressed mixture in the power stroke to force the piston down. Finally, in the exhaust stroke the exhaust valve opens and the piston pushes out the exhaust gases. The key components of a 4-stroke engine include the intake and exhaust valves, piston, spark plug, crankshaft, and camshaft.

Two stroke cycle engine
- Two-stroke engines complete the combustion cycle in two strokes of the piston rather than four strokes, as in four-stroke engines. They rely on crankcase compression or a blower to induct fresh air and remove exhaust gases, rather than separate intake and exhaust strokes.
- There are different types of two-stroke engines based on the scavenging method (crankcase or separately scavenged), scavenging process (cross flow, loop, uni-flow), and port timing (symmetrical or unsymmetrical).
- In a crankcase-scavenged engine, the piston helps induct fresh air into the crankcase and transfers it into the cylinder, where it scavenges out exhaust gases

Valve timing diagram
Valve timing is the precise timing of the opening and closing of valves in an internal combustion engine. It is controlled by the camshaft and can be varied by modifying the camshaft or using variable valve timing. With traditional fixed valve timing, engines experience a period of valve overlap when both intake and exhaust valves are open simultaneously. Variable valve timing uses computer control and oil pressure to advance or retard cam timing while the engine is running, changing valve duration, overlap, and sometimes lift. It has been implemented in many Japanese and European engines since the 1980s-1990s and more recently in some American engines.

Key components are the cylinders which compress the gas, valves which regulate gas flow into and out of the cylinders, and connecting components like the piston rods, crossheads and crankshaft which convert rotational motion to linear motion to drive the pistons. The document discusses design considerations and specifications for each major component.
4 stroke engine
The document describes the operation of a four-stroke engine, including the intake, compression, power, and exhaust strokes in one revolution of the crankshaft. It also discusses the valve timing and fuel injection systems. The cooling, lubrication, and timing systems are described as well as differences between gasoline and diesel engines.
Chapter 03 cmsm
This document provides an overview of engine design and operation topics that will be covered in Chapter 3, including the four strokes of a four-stroke engine, compression ratio, camshaft and valvetrain components, cylinder bore and stroke, engine classifications, and the major components and functions of engine lubrication, cooling, and other systems. It lists learning objectives and introduces key terms and concepts to set up explanations that will be provided later in the chapter.
Chapter_4_HYDRAULIC final ppt presentation
This document describes the basic components of hydraulic and pneumatic systems. It discusses the key components of hydraulic systems which include an oil reservoir, oil pump, pressure relief valve, directional control valve, flow control valve, pressure control valve, and actuators. For pneumatic systems, it outlines the main components as an air compressor, heat exchanger, air dryer, and FRL (filter, regulator, lubricator) unit. It then compares the characteristics of hydraulic and pneumatic systems and provides examples of hydraulic and pneumatic symbols and different types of rotary actuators, valves, and motors used in these systems.
Internal combustion engine
Engine, classification of heat engine, classification of IC engine, component of IC engine, four stroke engine and 2- stroke engine, petrol and diesel engine, comparisons, terminology related to engine
Scavenging supercharging.pdf
The document discusses scavenging, supercharging, and exhaust systems in diesel engines. It provides details on:
1) The purpose and process of scavenging, including the stages of scavenging and types used such as uniflow and reverse flow.
2) The purpose and advantages of supercharging, including constant pressure and pulse turbocharging systems. Constant pressure turbocharging provides steady exhaust gas flow and turbine efficiency while pulse turbocharging extracts more energy from exhaust pulses.
3) The components and operation of marine turbochargers, including axial and radial flow designs, inward and outward bearing arrangements, and labyrinth seals.
Introduction to Spark ignition four stroke engine
The document describes the key components and working principle of a four-stroke spark ignition engine. It discusses the four strokes - intake, compression, power, and exhaust. For each stroke it explains what is happening within the engine cylinder as the piston moves up and down. The document also discusses valve timing diagrams and important engine cycles like the Otto cycle. It provides definitions for terms like valve overlap and lag. Thermodynamic laws related to engine operation like Boyle's law and Charles' law are also summarized.

- 3. PARTS AND THEIR FUNCTIONS • CYLINDER • CYLINDER HEAD • PISTON contains gas under pressure and guides the piston seal the working head of the cylinder and to permit entry and exit of gases face to receive gas pressure and transmit thrust to connecting rod
- 4. • PISTON RINGS • GUDGEON PIN • CONNECTING ROD • provides sealing fit between piston and cylinder • supports and allows the connecting rod to swivel • transmits the piston load to crank.converts reciprocating motion of piston into rotating motion of crankshaft
- 5. • FLYWHEEL • VALVES • Takes cares of fluctuations of speed during thermodynamic cycle • two valves are there inlet valve (admit the air or air fuel mixture into the cylinder) outlet (discharge the product of combustion)
- 6. • GOVERNOR • CARBURETTOR • The function of governor is to keep the speed of engine constant irrespective of the load on the engine • The function of carburettor is to atomise the fuel and mix as it enters the engine
- 7. • SPARK PLUG • The main function is to conduct the high potential from the ignition system into the combustion chamber
