The CE12 three-cylinder cast iron engine block produced by Positive Constant Power is used for extended-range electric vehicles. The main principle of extended-range electric vehicles is that a small displacement engine drives a generator to charge/generate electricity for the battery pack, and then the battery pack drives a driving motor to drive the model. This is the core element of extended-range electric vehicles. The advantage of extended-range electric vehicles is that they are equipped with internal combustion engines, but they can achieve power data and fuel consumption levels that cannot be achieved by engines with similar displacement.

The cylinder block is one of the most important parts in the automobile engine and even in the automobile. The machining quality of the engine directly affects the quality of the engine, and then affects the overall quality of the automobile. Therefore, the manufacturing and processing of the engine cylinder block has long been paid attention to by the automobile production enterprises. Engine cylinder block is the basic parts and skeleton of the engine, and also the basic parts of the engine assembly. The function of cylinder block is to support and ensure the accurate position of piston, connecting rod, crankshaft and other moving parts when they work, and ensure the ventilation, cooling and lubrication of the engine. Car engine cylinder block and crankcase often cast into one, called the cylinder block – crankcase. Because the cylinder block usually works in high temperature, high load, severe wear conditions, under the greater pressure, the force is complex. At the same time work under the immersion of gasoline, the working environment is humid.

The use of performance requirements of the cylinder: the working conditions of the cylinder determines that the cylinder must have high strength, high stiffness, high hardness, high wear resistance and good heat dissipation, at the same time to have a good sealing, leakage resistance, vibration reduction and so on.

The materials used in engine cylinder block are generally gray cast iron, cast aluminum or cast steel. The use of gray cast iron can meet the requirements of high strength, high stiffness and high wear resistance, and the process performance, shock absorption, excellent machinability, and low cost.

We are a professional engine cylinder block manufacturer from China, has accumulated more than 20 million cylinder blocks, wholesale quality products, according to the engine cylinder block drawing co-research and development and manufacturing, we have professional technical team support and perfect after-sales service. Look forward to working with you!
