Patent attributes
An efficient engine combustion system with multiple combustion modes, includes a valve actuating mechanism, a pre-combustion chamber, and a main combustion chamber. The valve actuating mechanism is a fully variable valve mechanism; an intake valve and an exhaust valve are driven by high-pressure oil; ignition is implemented by means of an ignition apparatus of the pre-combustion chamber; and a spark plug and a single-hole fuel injector are mounted in the pre-combustion chamber, a bottom end of which is provided with a flame jet hole. The continuous variable of valve timing and real-time adjustment of valve lift are realized by the control of a three-position four-way servo valve, driven by the high-pressure oil and monitored by a displacement sensor. The efficient engine combustion system with multiple combustion modes employs different combustion modes under different engine conditions, so as to ensure optimal thermal efficiency under different operating condition regions.
