Outline
The catalytic converter makes harmful substances (CO, HC and NOx) react chemically with harmless ones (H2O, CO2, N2) according to the exhaust gas passed. Generally platinum, palladium, iridium Read more What is an Automotive Catalytic Converters?
Emission control regulations
There are various regulations for most countries around the world today to prevent the air pollutants by emission gases. These are called emission regulations. The measurement Read more Automotive Emission Standards
Theoretical Air-fuel Ratio
The theoretical air-fuel ratio is the ratio of the minimum amount of fuel and air (which contains oxygen) needed to fully burn the fuel. Gasoline is a mixture of several types Read more Principle of Production of Exhaust Gases
It is best if the temperature of the engine oil does not rise above 100C. If the temperature rises above 125C however, engine oil lubrication properties will deteriorate suddenly. Therefore, to maintain Read more Engine Oil Cooler
1. What is emission control system?
The emission control system reduces the emissions, which are harmful to the environment and human beings produced by automobiles.
2. What are emissions?
The vacuum advancer controls the timing advance in accordance with the engine load. The diaphragm is connected to the breaker plate via the rod or carburetor. The diaphragm chamber connects the advance Read more Vacuum advancer
The governor advancer controls the timing advance in accordance with the engine speed. Ordinarily, the position of the governor weights is determined by their springs. As the speed of the distributor shaft Read more Governor advancer
This ignition device consists of an igniter and an ignition coil that is integrated into a single unit. In the past, high-voltage current was sent to the cylinders via high-tension cords. Now, an ignition Read more Ignition coil united with igniter
Timing Chain Auto-tensioner
The timing chain auto-tensioner uses a spring and engine oil pressure to maintain proper tension at all times. It also suppresses noise from the timing chain. Using an internal Read more Engine Auto Tensioner
The engine ECU, which receives signals from various sensors, calculates the ignition timing and transmits ignition signals to the igniter. The ignition timing is calculated continuously in accordance with Read more ESA (Electronic Spark Advance)
