* Engine in-cylinder braking - a new method of engine compression braking The Global trade intelligence newsletterengine is the core component of the automobile. It is a device that converts other energy into mechanical energy.When we drive or brake, the engine consumes a lot of fuel, and when braking, we often use horn braking, engine braking, braking and other methods. Among them, horn braking achieves the effect of allowing pedestrians or vehicles to hear the alarm and slow down by continuously honking, while engine braking refers to removing the accelerator pedal to achieve the effect of slowing down. In engine braking, the rover effect is usually caused by compression braking in the engine cylinder. In order to solve this problem, engine in-cylinder braking has become a braking method in the new era. I. The principle of engine in-cylinder braking. The engine in-cylinder braking is to use the working principle of the engine to close the intake valve and exhaust valve at the same time when the engine is not supplying oil. The piston is used to carry out reciprocate movement in the cylinder, and the air in the cylinder is squeezed to the top of the cylinder to compress it. Due to the increase in the density of the air, the engine is pressed Slow down by shrinking and braking.Under the condition of low speed, the use of in-cylinder brakes can significantly reduce the wear of brake pads, and the economy will also be improved to a certain extent. II. Advantages of engine in-cylinder braking 1. Alleviate the handling effect: The use of in-cylinder braking of the engine can reduce the wear of the brake pads, while avoiding the driver from stepping on the brake for a long time, reducing the burden of the brake system, and alleviating the handling effect during driving. Two. Mechanical braking is more powerful: engine in-cylinder braking can combine the compression effect of the engine itself with the principle of mechanical braking of the brake pedal, so that the braking effect of the vehicle is stronger and the sensitivity of the brake is also improved. 3. Economical and energy-saving: The use of engine in-cylinder braking can significantly reduce fuel consumption and exhaust emissions, so as to achieve the effect of energy saving and environmental protection while having mechanical braking.III. Scope of application of engine in-cylinder braking Engine in-cylinder braking is suitable for the process of slowing down at low speed. Generally, this deceleration method is suitable for urban roads, mountainous highways, etc., while for highways with complex road conditions, the effect of in-cylinder braking is usually relatively weak, and it needs to be combined with brakes to achieve rapid braking. IV. Precautions 1. Engine in-cylinder braking should not be used under high-speed driving, sharp turns and other conditions to avoid accidents. Two. There are certain restrictions on the scope of application of engine braking, and it is not suitable for complex road conditions such as long-term high-speed driving and steep mountain roads. 3. When using engine in-cylinder braking, you should pay attention to whether the brake light is on normally, so as to indicate your intention to slow down to the rear car. Conclusion With the continuous development of technology, engine in-cylinder braking has become a new era.The new technology of carbon emission reduction can not only effectively solve the problem of the puncer effect caused by engine braking, but also improve the economy, energy saving and environmental protection performance of driving. However, at the same time, we should pay attention to the scope and limitations of the use of the in-cylinder brake of the engine, and follow the safety and driving habits, so as to ensure the safety and efficiency of driving.
