摘要:
In a liquid cooled cylinder head for a multi-cylinder internal combustion engine including in the cylinder head a cooling water space which is divided into cooling water space sections each disposed above one of the combustion chambers formed in the cylinder head bottom, a trapezoid-shaped cooling water flow control rib element projects from the cylinder head top above each combustion chamber in a plane extending essentially normal to the flow direction of the cooling water in the cylinder head such that the cooling water is deflected onto the cylinder head bottom above the respective combustion chambers.

A device for preventing an accelerator from being erroneously operated when an accelerator pedal of a motor vehicle is erroneously pushed down includes a magnetic coupling device comprising an accelerator interlocking member interlocking with an accelerator pedal and a throttle interlocking member connected to a throttle cable. When the accelerator pedal is pushed down during normal operation the throttle cable is operated through the magnetic coupling device to cause the motor vehicle to be accelerated. When the accelerator pedal (14) is erroneously pushed down in spite of the brake pedal being intended to be pushed down, the magnetic coupling device decouples and prevents the throttle valve from being operated and the motor vehicle from being accelerated.

A particulate and exhaust emission control system for a vehicle (10) having a diesel engine (12). The control system has a particulate trap (24) connected to the exhaust manifold (22) of the diesel engine, an additive tank (30) for storing a fuel additive decomposed by the engine's combustion process to form a reducible metal oxide capable of depressing the ignition temperature of the carbon particulates collected by the particulate trap (24) and a metering mechanism (34) responsive to the adding of diesel fuel to the vehicle's fuel tank (28) to add a quantity of the fuel additive to the diesel fuel in the fuel tank (28) to maintain a predetermined ratio of the fuel additive to the diesel fuel in the tank. The metal oxide depressing the ignition temperature of the carbon particulates collected by the particulate trap (24) to a temperature obtained by the particulate trap during selected operating parameters of the diesel engine (12). The particulate trap (24) includes a honeycomb ceramic filter element (38) having inlet channels (44) for collecting the carbon particulate and exit channels (46) coated with a catalyst to oxidize carbon monoxide and unburned hydrocarbons in the exhaust.
摘要:
A vehicle is equipped with an engine control ECU, an anti-lock brake system control ECU, a transmission control ECU and a meter control ECU. Each ECU shares information with the others by communicating and by performing mutual malfunction diagnosis operations through communication; also, backup operations are performed. After the deactuation of the ignition switch, malfunction diagnosis operations are prohibited by prohibiting communication between the engine control ECU which is supplied with electric power and the other ECUs which are not supplied with electric power. After the deactuation of the ignition switch, when a predetermined time lapses after the actuation of the ignition switch from the state wherein the ECU is supplied with power, prohibition on communication with ECUs is released.
摘要:
The invention concerns a two-stroke internal combustion engine and a method of operating a two-stroke internal combustion engine which includes at least one cylinder (10) with a piston (20) reciprocating therein and with at least one inlet (40) and exhaust duct (70), wherein the inlet duct (40) is arranged in relation to the exhaust duct (70) in accordance with the uniflow scavenging process in such a way that the inlet duct (40) opens into the cylinder in the region of the combustion chamber (30) and wherein a regulating element (50) is provided in the mouth opening region of the inlet duct (40). In that arrangement the regulating element (50) of the inlet duct (40) can be adapted to be controllable and a controllable regulating element (80) can also be arranged in particular in the mouth opening region of the exhaust duct (70). As a result the internal combustion engine can be operated in such a way that the exhaust duct (70) can be closed in dependence on an operating parameter of the internal combustion engine.

A lubricant supply system is provided for the induction system of a marine propulsion engine. The lubricant supply system delivers lubricant to the a flow controlling valve in the induction system upon shutting down of the engine and can be operated manually at the discretion of a user. The lubricant serves to reduce the likelihood of post-operation corrosion of the valve, particularly at the sliding support surfaces of the valve and also provides lubricant from start-up operation.
摘要:
The conventional gas turbine combustor is improved by mounting a pilot flame producing torch in a wall of the combustor to project a flame into the combustor as a means of ignition. The torch preferably is a catalytic igniter which will operate over a wide range of air/fuel ratios.

Electronic engine management systems have a plurality of individual components, some of which are relatively far away from one another. Electrically connecting the individual components, particularly to an electronic control unit therefore requires relatively long electrical connecting lines and relatively many plug connection. The apparatus includes a plurality of components, that is, at least one throttle device accommodated rotatably in a throttle valve housing and actuatable by a throttle valve control motor, an electronic control unit, a regenerating valve, and/or an air flow rate meter, which according to the invention are accommodated in a common housing as a premountable structural unit. The apparatus of the invention is intended in particular for mixture-compressing internal combustion engines with externally supplied ignition.
