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.

Abstract: Provided is a variable valve device for an internal combustion engine. The variable valve device includes intake- and exhaust-side swing arms that pivot to open and close intake valves and exhaust valves in two cylinders #1, #2, intake- and exhaust-side hydraulic lash adjusters that serve as pivot points of the respective swing arms, a variable valve system that continuously varies valve lift characteristics of the intake valves and lost motion mechanisms that stop opening and closing of the intake exhaust valves by lost motion of the intake- and exhaust-side hydraulic lash adjusters on the cylinder #1. The maximum valve lifts of the intake valves are set larger than valve lifts of the exhaust valves. The minimum valve lifts of the intake valves are set smaller than the valve lifts of the exhaust valves.

Abstract: The angular timing relationship of the cams opening and closing the inlet and exhaust valves of an internal combustion engine can be varied while the engine is running to improve combustion efficiency. The angular relationship is varied by shifting of idler rollers 78, 80 acting on the camshaft driving timing chain adjusted by providing two cams 108, 110 for the same valve intake 104 so that cam 108 controls opening and cam 110 controls closing. Exhaust valve 105 has its opening controlled by cam 115 and its closing controlled by cam 113. An idler 122 between the two camshafts controlling cams 110 and 115 acts on the timing chain. The timing is also varied by moving the pivot point 104 of the rocker arm 62 to obtain later closing of the inlet and earlier opening of the exhaust valve 46 at high speed. Valve timing and duration is also controlled by adjusting the length of the push rod 108 and its point of contact with rocker arm 62.
