The Four Stroke Cycle. As long as the engine is running, it will continue to repeat the four steps in a four-stroke cycle continuously. Each step in the cycle represents a 180° movement of the piston which corresponds to a half-revolution of the crankshaft. Since it takes two crankshaft revolutions to complete one four-stroke cycle, the 6-Month Maintenance Schedule. At the six-month mark, you’ll have more intensive checks to do. Clean the crankcase breather. The crankcase breather releases any gases that become trapped in the engine compartment, reducing the pressure in the engine. This piece reroutes the gases into the carburetor. Modern cars are designed to have a constant through-flow of fresh air that keeps the interior atmosphere pleasant even with all the windows shut. The incoming air can be heated by the engine to keep the windows clear of mist and the car interior at a chosen temperature. Read more. Basics. 16 Simple Step’s To Start Marine Engine. Start another generator and take it on load. Start all the lube oil, fuel oil and jacket water pumps and maintain their required temperature and pressure. Ensure fuel and lube oil purifiers running. Check oil level in sump and turbocharger. The Four-Stroke petrol engine works on the following cycle which includes –. 1. Suction Stroke – With pistons moving downwards and the opening of the inlet valve creates the suction of air-fuel mixture. Petrol Suction Stroke. 2. Compression Stroke – With the closing of Inlet valve, it closes the area above the piston. Diesel engines work differently than gasoline engines, although the role of the fuel injectors remains basically the same. Diesel engines don't use a throttle. Instead, when you step on the accelerator, more fuel is pumped to the injectors, and that is what speeds the engine up. Diesel engines have used direct injection right from the start. Step 3: Disassembly Part 1: Engine & Accessory Removal/Labeling System. Alright, time to get to the disassembly of the engine. If your engine is already in a car you will need to use an engine hoist to remove it from the engine bay. Then it can be placed on an engine stand. Diesel engines operate on the principle of compression ignition, where the air-fuel mixture is compressed to a high pressure and temperature, causing spontaneous combustion. This combustion process allows diesel engines to extract more energy from the fuel compared to gasoline engines. The efficiency of a diesel engine is influenced by several .
