Cylinder liner &materials
The document discusses cylinder liner materials used in engines. Common materials include nitrided steels, nitrided cast irons, and heat treated chromium and alloy cast irons. These materials provide at least 50% more wear resistance than the cylinder block material. A typical specification for liner material lists its composition as iron comprising 93.92-92.22%, carbon at 3-3.5%, silicon at 1.8-2.4%, manganese at 0.5-0.8%, phosphorus at 0.4-0.7%, sulfur at 0.08%, and chromium at 0.3%.
10 cylinder liners and piston ring manufacturing
The cylinder liner is cast separately from the cylinder block and can be made of a different, more durable material like a nodular cast iron alloyed with chromium, vanadium, and molybdenum. While the cylinder block is made of grey cast iron, the liner wears with use and may need replacement, unlike the cylinder jacket that lasts the life of the engine. Piston rings are split rings that fit into grooves on the outer diameter of engine pistons to seal the combustion chamber.
10 cylinder liner and rings
This document discusses various components of internal combustion engines including pistons, piston rings, connecting rods, and their materials and functions. It provides details on piston design types, materials, manufacturing processes, ring materials and compositions. It also describes connecting rod designs, materials, measurements and installation procedures. The key components and their roles in transforming combustion energy to rotational motion are summarized.
9 upset forging of valves
Upset forging is a common forging process that increases the diameter of a workpiece by compressing its length. It is widely used to produce engine valves, couplings, bolts, and screws. The process is typically done in high-speed crank presses and is suitable for producing parts like valves from titanium or austenitic steel alloys.
8 gudgeon pin
The gudgeon pin, also known as a piston pin, is a pin that holds the piston rod and connecting rod together in an engine. It is typically made from a high strength and hardness steel alloy and can be physically separated from both the connecting rod and piston. The gudgeon pin is a short hollow rod that connects the piston to the connecting rod.
7 connecting rod
The document discusses materials used for connecting rods. Steel alloys like 42CrMo4, 43CrMo4, 44csr4, C-70, EN-8D, and SAE1141 are commonly used as they are usually drop forged from steel. Aluminum and titanium are also sometimes used for connecting rods in high performance vehicles due to their lighter weight.
6 crank shaft
The crankshaft is usually made of medium-carbon steel alloys composed of iron with a small percentage of carbon between 0.25% and 0.45%, along with various alloying elements mixed in to strengthen the material.
5 cylinder head
The cylinder head determines key engine properties like power output, torque, and emissions. Cylinder heads require materials with high mechanical properties above 150°C due to the complex shapes and high stresses during operation. For passenger cars, aluminum is commonly used due to its properties, while cast iron is used for larger engines. Modern cylinder heads, especially for direct injection diesel engines, require alloys with high tensile strength, creep resistance up to 250°C, thermal conductivity, and ductility to withstand thermal stresses. Common casting methods include sand casting, permanent mold casting, lost foam, and pressure die-casting, using cast iron or aluminum alloys.
4 engine block
The document discusses the manufacturing process of engine components. It describes the steps as:
1. Casting of the engine block using conventional or expendable patterns. Other components like cylinder heads, crankshafts and connecting rods are also cast or forged.
2. The castings undergo machining and heat treatment processes. Pistons are manufactured through gravity casting, squeeze casting, and then machined.
3. Valves are upset forged and heat treated to improve strength and wear resistance. Cylinder liners and piston rings are also manufactured to complete the engine assembly.
3 surface hardening
Case hardening or surface hardening involves hardening just the surface of a metal part to create a thin hardened outer "case" while leaving the inner core soft. There are several methods for case hardening, including direct hardening using austenitizing and quenching, as well as diffusion hardening techniques like carburizing (adding carbon via heating in a carbon-rich environment), nitriding (diffusing nitrogen into the surface at high heat), and cyaniding (dipping in a heated cyanide bath). Carburizing, the most common diffusion method, involves packing parts in charcoal and heating to diffuse carbon atoms into the surface before quenching.
3 forging
Forging is the process of shaping metals by applying compressive forces. It can be done either hot or cold. Common forging operations include drawing, piercing, punching, and swaging. Forging machines include drop hammers, power hammers, mechanical presses, and hydraulic presses. Closed-die forging uses dies to precisely shape parts, while open-die forging uses simpler dies. Proper die material selection and coatings can increase die life. Forging results in an elongated grain structure and improved mechanical properties compared to casting.
2 basics of casting
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
2 introduction to cim. pptx
Computer integrated manufacturing (CIM) is an approach that uses computers to control the entire manufacturing process. In a CIM system, functions like design, planning, cost accounting, and inventory control are linked through computers to factory floor functions like materials handling and operations management to provide direct monitoring and control of all operations. CIM allows processes to exchange information and initiate actions, enabling faster, less error-prone manufacturing and the creation of automated processes. The benefits of CIM include improved quality, shorter new product times, minimized costs and flow times, increased competitiveness, flexibility, productivity and customer service.
3 numerical control

1) The historical development of NC from mechanized production equipment to programmable automation using NC, PLCs, and robots.
2) The basic definition and components of an NC machine, including the numerical controller, NC code, and interactions between the operator and machine.
3) The main components of NC machines - the machine control unit, machine tool, and various control units. It also discusses different types of machine control units.
4) Key aspects of NC motion control including point-to-point and continuous path control, open and closed loop systems, and different
5 accuracy and productivity
This document discusses methods for improving machine accuracy and productivity. It focuses on tool deflection, lead screw accuracy, and thermal deformation for improving accuracy. For productivity, it examines actual cutting time, idle time, loading/unloading time, and tool changing time. The document also provides an overview of special tool holders, describing the main parts of tool holders and different types like boring heads, chucks, and adapters. It emphasizes the benefits of balanced, high-accuracy tool holders for optimizing performance on CNC machines.
3 tyre types
This document discusses different types of tires. There are two main types - tubed tires which have an inner tube, and tubeless tires which do not have an inner tube. Tubeless tires have advantages like lesser weight, better cooling, lower rolling resistance, and more comfortable ride.
The document also describes different tire constructions - cross-ply/bias ply tires which have fabric plies laid across each other at alternating angles, radial ply tires which have fabric arcs from bead to bead at 90 degree angles, and belted bias ply tires which have belt plies reinforced with wire. Radial ply tires provide benefits like better shock absorption and fuel efficiency compared to cross-ply tires.
1 wheels
The document summarizes wheels and tires. It discusses the requirements of automobile wheels, including being strong, balanced, lightweight, and easy to remove/mount. Standard wheels are steel, while some vehicles use aluminum or magnesium alloy wheels. Valve stems allow inflation/deflation and retain air. Wheel studs and nuts attach wheels to hubs using correct torque for safety. Common wheel types include steel, alloy, spoke, divided, and split rims. Custom wheels come in aluminum variants and differ in offset for handling characteristics.
3 tyre materials
The document discusses the materials used in car tires, including nylon, polyester, rayon, carbon black, and aramid fibers for the carcass and belts. It also discusses the components of tires like raw rubber, steel, and synthetic rubber. The aspect ratio and tire specifications are explained. Factors that affect tire life and common tire issues are outlined. The manufacturing of pneumatic tires filled with compressed air is also briefly discussed.
4 tyre pressure and defects
Tire pressure should be checked monthly when cold and adjusted according to temperature, as it can affect mileage. Nitrogen is better than oxygen in tires as it leaks out more slowly and prevents rust and oxidation of rubber and steel. Proper inflation prevents uneven and accelerated tire wear from under or over inflation. Tire defects like separations, bulges, cracks or tears can cause safety issues and should be addressed.
2 tyre
John Dunlop invented the first pneumatic tire in 1888, replacing solid tires. Tires are black because UV stabilizers are added to rubber to absorb harmful UV rays. A tire consists of an outer cover and inner tube that is mounted over a wheel rim. Air inside the tube supports the vehicle's weight and provides cushioning. Desirable tire properties include being non-skidding, wearing uniformly, carrying loads, cushioning impacts, minimizing power consumption, keeping noise low, and maintaining balance.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
