    摘要: An annoying problem with diesel engines is combustion noise especially under high speed, low load conditions. The problem is caused by the relatively long ignition delay period or the period of time from the start of fuel injection into the combustion chamber until ignition occurs. The length of the ignition delay period influences the severity of the noise produced as it determines the amount of fuel that is ready to be burned. The length of the ignition delay period is strongly dependent on cylinder gas temperature during the initial part of the fuel injection schedule. The present invention provides an apparatus to reduce the ignition delay period by elevating the temperature of the air in a selected one of the combustion chambers so that at the start of the compression stroke the air is elevated reducing the ignition delay period.

    摘要: Braking systems for use with internal combustion engine have in the past used a variety of mechanical mechanisms to activate the braking system in addition to the conventional cam, lifters, pushrods and rocker arms. Many of these systems fail to provide the option of controllably and modulatively varying the sequence and amount of the opening and closing of an intake or exhaust valve relative to a piston position in a cylinder bore. The present invention provides an electronic control system outputting an discrete control signal, an opening device for unit actuation of each of the pair of valves independently. The electronic control system is programmable to respond in a first predetermined logic pattern for conventional operation of the engine at which time each of the pair of valves are in the closed position during the compression stroke. The electronic control system is programmable to a second predetermined logic pattern to vary the operation of the valves associated with the respective bore in the generally open position during the compression stroke when the piston in near the top dead center position. The preestablished logic pattern controllably, sequentially and modulateably actuate the device for unit actuation, moving each of the valves independently between the open and closed position to effectively resist the movement of a piston from a bottom dead center position to a top dead center position.

    摘要: Starting systems for use with internal combustion engine have in the past used a variety of add on mechanical mechanisms to provide cold starting. Many of these systems fail to provide the option of controllably and modulatively varying the sequence and amount of the opening and closing of an intake or exhaust valve relative to a piston position in a cylinder bore. The present invention provides an electronic control system outputting an discrete control signal, and an opening device for unit actuation of each of the pair of valves independently. The electronic control system is programmable to respond in a first predetermined logic pattern for conventional operation of the engine at which time each of the pair of valves is in the open position during the exhaust stroke. The electronic control system is programmable to a second predetermined logic pattern to vary the operation of the valves associated with the respective bore in the generally closed position for a portion of the exhaust stroke before top dead center during the exhaust stroke of the piston. The preestablished logic pattern controllably, sequentially and modulateably actuate the device for unit actuation, moving each of the valves independently between the open and closed position to effectively increase the heat within the during the movement of a piston from a bottom dead center position to a top dead center position.

    摘要: A closed loop control system for an exhaust gas recovery flow in an internal combustion engine having an intake air pressurizing device is provided. The closed loop control system includes an engine controller connected to an intake air mass flow sensor, an engine operation sensor, and an intake air throttle valve for controlling the intake air mass flow rate. In addition, the controller is operatively connected to a variable gas pocket valve for selectively controlling exhaust gas feedback in conjunction with the intake air throttle valve. The variable gas pocket valve and the intake air throttle valve may be actuated in response to the control system parameters to provide accurate control of exhaust gas recovery flow to provide reduced emissions of unburned fuel and particulate matter from the engine.

    摘要: Multiple intake valves operatively associated in a common combustion chamber are advantageous in that the design achieves high output for an internal combustion engine. The subject modified cylinder head utilizes the advantages available in a multiple intake valve system, but further enhances the design by reducing heat rejection. In the subject modified cylinder head, three intake valves (38,40,42) having corresponding intake valve ports (26,28,30) and one exhaust valve (68) having an exhaust valve port (66) are operatively associated in a common combustion chamber. A reduction in heat rejection is achieved through a relationship between the cross-sectional areas of the intake and exhaust valve ports (26,28,30,66). The intake valve ports (26,28,30) are constructed so that their cross-sectional area is larger than about 69% of the combined cross-sectional area of the intake and the exhaust ports (26,28,30,66).

    摘要: A method of compression braking is provided for use in an internal combustion engine having a plurality of combustion chambers that share a common exhaust manifold, such as, for example, a six-cylinder engine. The method comprises the steps of moving each exhaust valve to an open position at a first time corresponding to approximately the beginning of the power portion of the cycle of the combustion chamber associated with the exhaust valve and moving each exhaust valve to the open position at a second time corresponding to approximately the end of the intake portion of the cycle of the combustion chamber associated with the exhaust valve.
