Car Engine
Cutway ofpiston receives cycle The four-stroke combustion petrol engine pressure;
The connecting rod transmits the combustion pressure to the crankshaft and the crankshaft transforms this reciprocating motion into smooth rotation. The combustion of the air-fuel mixture takes place in the chamber then moves up and down in the cylinder via combustion pressure and the combustion gas is then sealed by the piston of four-stroke operationsring, which contains the pressure. A valve system takes in and exhausts the combustion gas gas.

Recent Trends in Engine Technology
The in receives 1. To obtain higher output power, the multi-valve engine usedpistoncar engine combustion pressure; has increased The connecting rod transmits the combustion pressure to 2. The variable valve system has decreased fuel consumption the crankshaft and the 3. The multi-cylinder engine has become more widespread. It has a crankshaft transforms this reciprocating motion into smoother rotation to decrease noise and vibration smooth rotation. 4. Three-way catalysts (Pt-Pd-Rh alloy) technology, using The2combustion of the air-fuel O and knock sensors, has decreased the three components CO, HC mixture NOxplace theand and takes in in the chamber then moves up down in the cylinder via exhaust gas combustion pressure and the 5. Decreased inertial weight and electronic control have improvedgas is then sealed combustion engine by the piston ring, which performance contains the pressure. 6. Hybrid systems including an electric motor or fuel cell have reduced fuel A valve system takes in and exhausts the combustion gas gas. consumption 7. The use of diesel engines remains on a continuing upward trend due to high performance and favourable torque characteristics
