| 6540160 | Fuel injection device for an internal combustion engine A fuel injection device having a fuel pump for each cylinder of an internal combustion engine, which fuel pump has a pump piston that is driven into a stroke motion by the engine and delimits a pump working chamber, which is supplied with fuel from a fuel... | 04/01/2003 |
| 6431146 | Free piston engine and self-actuated fuel injector therefor A simple propulsion engine utilizing unheated atmospheric air as the propellant, and driven by a single cycle (unicycle) engine with internal combustion cylinder and free piston is disclosed. A free piston with an annularly arranged thrust piston to divid... | 08/13/2002 |
| 5924408 | Fuel metering system for sequentially feeding fuel to the cylinders of a combustion engine Fuel metering system for feeding fuel from a storage tank (2) to the cylinders (6) of a combustion engine (8), comprising a fuel supply unit (1) and a distributing device (4, 4', 4") which comprises a least one rotor driven depending on the rotational pos... | 07/20/1999 |
| 5889733 | Timer device for distributor type fuel injection apparatus In a timer device having a timer sleeve at a housing with a timer piston slidably provided at the timer sleeve, a high pressure chamber is constituted by securing to the housing a high pressure side cover member constituted as an integrated part of the ti... | 03/30/1999 |
| 4545345 | Air/fuel induction system for a multi-cylinder internal combustion engine An air/fuel induction system includes a pair of solenoid valves injecting fuel into an induction passage of a multi-cylinder engine. The valves supply fuel upstream of the inlet manifold to the engine and do not therefore direct fuel to specific cylinders... | 10/08/1985 |
| 4505245 | Fuel pumping apparatus A fuel pumping apparatus for supplying fuel to a multi-cylinder internal combustion engine includes a high pressure pump which supplies fuel in timed relationship with the engine. The fuel is distributed to fuel outlets in turn by means of an axially mova... | 03/19/1985 |
| 4374511 | Fuel injection pump with distributor type fuel control A fuel injection pump has a single plunger either electromagnetically or hydraulically actuated for flow of fuel into a fuel distribution chamber from which the fuel is distributed individually to each engine cylinder past a series of small solenoid contr... | 02/22/1983 |
| 4250857 | Fuel injector for producing shaped injection pulses A fuel injector, especially adapted for diesel engines, produces a fuel injection pulse having a predetermined time-variable flow rate. Preferably the injection pulse is ramp-shaped which approximates a linear function of time. A pressure chamber receives... | 02/17/1981 |
