Abstract: An efficient internal combustion engine including a housing such as a cylinder block, cylinder covers and one or more pairs of working piston and auxiliary piston, moving in the working cylinder and auxiliary cylinder respectively. For each pair of working piston and auxiliary piston, the engine also has rods operatively connected to working piston and auxiliary piston, intake valve, operatively connected to the intake channel in the cylinder block, exhaust valve, operatively connected to the exhaust channel in the cylinder block, and two bypass valves located between the working cylinder and auxiliary cylinder. The engine also has a crankshaft that also functions as a camshaft, rod pushers for pushing special nozzles and valves, flywheel, Hydro-compensators and preferably a high pressure fuel pump (HPFP). No cylinder heads or separate camshafts are used in the present invention.tle

Abstract: A fuel pump includes: a housing with fuel reservoir; first and second axles; respective pluralities of cams fixedly secured to each axle. The first axle and cams are rotated by gas pedal actuation, and meshed gears cause co-rotation of the second axle and its cams. A plurality of housing conduits each have first conduit portions in fluid communication with the fuel reservoir, which transition into second conduit portions in fluid communication with a fuel injector. Pusher rods slidable in each second conduit portion contact spring-biased balls. The gears, cams, and pusher rods ends are positioned in the fuel reservoir. Spring-biased balls also normally block the first conduits. Rotation of the first axle for increased crankshaft rotation speed causes simultaneous rotation of every cam, and each increment of cam rotation into second, third, fourth, and fifth rotational positions sequentially drives a respective pusher rod to provide incremental increased fuel flow.
