D 800 Engine 3D Model
Engine 3D Models are graphical representations of internal combustion engines. They are comprised of several parts including cylinders, pistons, crankshafts, and camshafts.
Engine 3D Model Configuration
The first step in modeling or searching for stock 3d models of engines is to determine the engine configuration and its use. The layout of the major components which include the cylinders, pistons, crankshafts and camshafts, determine the configuration of the engine.
Engines are typically classified according to their piston motion (single, inline, radial, piston-less), placement of their valves or the placement of their camshafts. A common classification of engines includes the four stroke engine, two stroke engine, piston-less rotary engine (Wankel), gas turbines, and jet engines.
Major Components of the Engine
After you have determined your engine configuration, the next step is to locate the major components on engine diagrams, photographs, digital images or still renders of 3d models. The location of the major components is mostly determined by the shape of the combined engine block and crankcase. Therefore, the location of the major components of the engine and its shape can help you search for and identify the type of engine you are looking for.
For example, when looking for a four-stroke engine, first identify the major components such as the crankshaft, connecting rod, camshafts, and the valves. Then, you can look for other components such as the piston, crank pin, and cylinders with spark plugs (on gasoline engines only). However, if you are looking for a two-stroke engine, look for an exhaust outlet and fuel inlet instead of looking for the valves.

Other engine components that can help you identify engines are the cooling, lubricating, engine control (startup), and exhaust systems.
The exhaust system is made up of devices that improve the efficiency of the engine and also control chemical and noise pollution.
For example, the exhaust system can quickly help you find a jet engine. This is because jet engines generate thrust via their exhaust system. Their exhaust has the shape of a high velocity nozzle which can be easily identified and compared to other engines when you browse through still renders of an engine 3d model.
Cooling systems can also help you identify certain types of engines. The cooling systems are typically made of components that use air or liquid to reduce high temperatures. Combustion generates a great deal of heat, and some of this heat transfers to the walls of the engine. If the engine overheats, then failure will occur because the engine will physically fail or the lubricants will degrade to the point that they will no longer be able to effectively protect the engine.
For example, the cooling system of rocket engines is different than that of automobile engines because they use the fuel to cool. Other high altitude engines use controlled and gradual loss of material to cool engine components.
Engine control systems can also help you discern engines. The components that make up the engine control enable the start and shutdown of the engine and control of the power, speed, torque, pollution, combustion temperature, efficiency. Many control systems today are digital, such as the on-board diagnostics, which are used to perform electronic diagnosis of a vehicle and tuning of the engine.
Understanding the major components and engine classification can greatly help you cut down time when looking for an engine 3d model or when you are modeling engines.
