Definition of diesel engine A diesel engine, also known as a compression-ignition engine, is a type of internal combustion engine that operates on the principle of compression ignition. In a diesel engine, fuel is injected into the combustion chamber at a high pressure. The fuel and air mixture is compressed by the piston, which raises the temperature inside the combustion chamber. This high tempe...

What is the reason for the engine valve not closing tightly? When engine valves do not close tightly, it can be attributed to several potential reasons: 1.Valve Clearance Issues: Each engine valve has a specified clearance range that allows for expansion due to heat. If the valve clearance is too large, the valve may not close tightly, resulting in a loss of compression. Regular valve clearance ad...
