A new hydrogen direct-injection SI engine employing a rhombic link Z-crankshaft mechanism has been developed. The engine was operated for a single combustion cycle. Experimental results show that Z-crankshaft engine keeps relatively high pressure under condition of late spark timing due to piston motion caused by the mechanism. Ignition during injection period results in lower initial pressure rise, which means that rapid combustion of hydrogen can be controled by diffusion burning of hydrogen jet. Neumerical simulation shows that Z-crankshaft engine is useful, in particular, under high speed operating condition for hydrogen combustion because this engine reduces pressure rise with keeping high power when engine speed is increased.
