VVKB factory has passed TUV certification to ensure the reliable product quality The harsh driving conditions in winter can be a test for the engine. If you need to drive in the early morning, it will make things worse. All you need to do before starting the engine is to preheat the engine with VVKB Titan-P5 engine preheater. Regarding the diesel engine, it requires higher temperatures to ignite smoothly, due to its performance. Therefore, when in cold weather, diesel engines are usually more difficult to start than gasoline engines. To make the diesel engine easier to start, VVKB has developed an engine preheater that can warm up the engine before it starts--That is VVKB Titan-P5 engine preheater. Regarding the gasoline vehicle, normally the mixture of gasoline and air enters the cylinder(combustion chamber of the engine). The piston compresses the mixed gas; the glow pin works; the mixed air is burned, and then the power outputs. When the gasoline engine is started in the morning at low temperature in winter, its difficult for the gasoline to be completely atomized. The exhaust gas passes through the sensor, and the fuel is insufficient, which will increase the supply of fuel. This arises a serious problem. In fact, the additional fuel cannot be completely burned. They are deposited on the cylinder liner. The cylinder liner is lubricated, so gas will clean away the lubrication between the cylinder liner and the piston. This kind of cleaning can adversely affect the lubrication and life use of piston rings and cylinder liners over time. Therefore, it is very necessary to preheat the engine in the winter morning. It allows the engine to return to normal condition as soon as possible.
