New split-cycle concept to control diesel HCCI combustion

Green Car Congress

The turbocharged concept allows reaching engine speeds of 6,000 rpm, with a high indicated efficiency of 45% along with clean combustion; power density at 6,000 rpm is 64 kW, with 300 kPa intake pressure. Thus the HCPC range can extend to all engine operating conditions, including very high loads. —Musu et al., Tamagna, D.,

Dalian team proposes jet controlled compression ignition to control PCCI phasing in a hybrid pneumatic engine

Green Car Congress

It compresses the pressurized gas produced by exhaust gas turbocharger, comprising fresh air and exhaust gas introduced from the EGR valve. High-pressure air supplied from a compressed air storage tank is jetted into the power cylinder through a high-pressure air jet system near TDC.
