NetEase Xinjiang Urumqi netizen?: Brand-new hcci engine. Currently, China’s energy-saving engine patented technology has successfully achieved various indicators in hcci engines. Patent name: Intake and exhaust interconnected piston supercharged engine , Patent number: 201120375693.4. This patent is when the engine is closed, through the intake and exhaust connecting pipes, the air in the closed cylinder is injected into the working cylinder next to it, and the compression ratio of the working cylinder is increased, so that no ignition is required (no ignition is required) Use spark plug ignition) to achieve the purpose of gasoline compression ignition, and the heat energy utilization efficiency is improved in detail, which is 30% higher than that of ordinary engines. In the energy-saving (cylinder closed) state, when the piston rotates around the crankshaft, it will still inhale Fresh air, this technology cleverly uses the circulation of air in the engine to achieve the requirements for homogeneous air in the hcci engine, and the engine does not change much. The engine runs more smoothly in the closed cylinder state. When the cylinder closed state is cancelled, At this time, all spark plugs of the engine ignite and enter normal displacement conditions. In the closed-cylinder state, the engine's maximum speed is above 4,000, which is fully capable of reaching the current maximum speed of 120/hour limited by Chinese highways. The engine can easily switch and operate from normal combustion conditions to closed-cylinder hcci conditions through various sensors.
