A gasoline engine produces power through the explosion of a mixture of gasoline and air. The three essential elements for a gasoline engine to produce power are the following
1. Good air-fuel mixture
2. Read more Computer Control of Gasoline Engine

What is Diesel Knock and Gasoline Knock ?
The fuel accumulated during the ignition delay period is burned at one time during the flame propagation period. Thus the pressure inside the combustion chamber rises sharply. The pressure inside the combustion Read more What is Diesel Knock and Gasoline Knock ?
CO/HC Inspection and Adjustment
1. Necessity
Determination of engine condition. By measuring CO/HC, it is possible to determine the engine condition, including the effectiveness of the airfuel ratio, and the operation of the emission Read more CO/HC Inspection and Adjustment
What is an Automotive Catalytic Converters?
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?
Principle of Production of Exhaust Gases
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
Harmful Gases Produced by Automobiles
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?
Elements of a Gasoline Engine
All gasoline engines mounted on Toyota automobiles are four-stroke engines. Four-stroke engines operate by continuous and regular repetition of the following sequence:
1. Intake stroke
2. Compression Read more Elements of a Gasoline Engine
What is a GoodEngine Compression?
Necessity of compressing the airfuel mixture
When an uncompressed air-fuel mixture is ignited, it burns slowly due to the low density of fuel and air. However, when compressed air-fuel mixture is ignited, Read more What is a GoodEngine Compression?
Engine Cylinder Head
The cylinder head is located on top of the cylinder block. The bottom of the cylinder head is indented and combines with the piston to form the combustion chamber. Internally, there are a oil hole and Read more Engine Cylinder Head
EnginePlastic Region Bolt
The plastic region bolt is used in such areas as the cylinder head or bearing cap assembly to provide a steady bolt tension. Normally bolts are tightened to the elastic region. In this condition, the bolt Read more EnginePlastic Region Bolt
