  • Patent number: 9284916
    Abstract: In a method for operating a reciprocating-piston internal combustion engine having internal exhaust gas energy recuperation, a cylinder head recuperator is heated up during an exhaust cycle by hot exhaust gas flowing through the cylinder head recuperator prior to being exhausted from the cylinder via an exhaust valve. During an intake cycle, fresh charge flows into the power chamber of the cylinder by passing around a cylinder head recuperator. During the subsequent compression stroke, the cylinder head recuperator is moved out of a recess formed in the cylinder head such that some of the compressed charge can flow into the recess. Near the end of the compression stroke, the cylinder head recuperator is moved back into the recess so that compressed charge located in the recess is forced to flow through the hot cylinder head recuperator and thereby be heated up immediately before ignition of the compressed charge.

A negative pressure passage for a brake booster is connected to the air ejector at a side of suction gas via a check valve. A passage for PCV gas and an intake air branched passage for bifurcating a part of the intake air from a surge tank at an upstream side of the throttle valve are connected to a driving gas side of the air ejector, wherein a negative pressure control valve is provided in the intake air branched passage. The PCV gas and the part of the intake air are forced to flow into the driving gas side of the air ejector, so that the air ejector functions as a vacuum pump. As a result, the braking negative pressure for the brake booster can be surely reduced to a target negative pressure.

  • Patent number: 8006672
    Abstract: A method for starting an internal combustion engine under cold conditions. The intake manifold throttle valve is held closed and spark ignition is suspended. Fuel and air are admitted into the cylinders and the pistons are cranked for a plurality of revolutions. During each engine revolution cycle, the fuel/air mixture is compressed and heated adiabatically by the energy of the engine starter motor, and the mixture is exhausted into the exhaust manifold. During valve overlap a portion of the mixture is withdrawn into the cylinder and recompressed in the next cycle. Additional fuel may be injected to replace lost fuel. After several engine cycles, the fuel/air mixture becomes heated to a temperature above the flashpoint of the mixture. Sparking is re-established to fire the warmed mixture, and the intake throttle valve is re-enabled. The first firing can provide sufficient heat to continue spark-firing of newly-introduced mixture thereafter.

  • Patent number: 7934490
    Abstract: An engine ECU stores a map in which three regions, that is, a high-temperature region, a low-temperature region, and a region therebetween, are prescribed. The pre-feed time T set when the present condition falls in the region is the longest. An engine ECU executes a program that includes the step of detecting an engine cooling water temperature THW when the start-up of the engine is requested, the step of executing the pre-feed until the fuel pressure P becomes equal to or greater than a fuel pressure threshold value P(TH), and the step of starting the cranking when the fuel pressure P becomes equal to or greater than the fuel pressure threshold value P(TH). Thus, the bad start-up caused by fuel vapor is avoided without operating the fuel pump unnecessarily for a long time.

  • Patent number: 7841322
    Abstract: The instant invention provides an apparatus and system for cooling the air charge of an internal combustion engine. More specifically, the instant invention provides an air-induction system suitable to provide cooled air charges to turbocharged, supercharged or naturally aspirated internal combustion engines to increase power output while reducing engine emissions. The system utilizes gaseous fuel stored as a liquid wherein the liquefied gaseous fuel is vaporized and warmed at least partially with heat removed from the intake air charge supplied to the engine from the turbocharger or supercharger. In a preferred embodiment, the compressed intake combustion air is first cooled in an aftercooler against an ambiently cooled coolant and is subsequently cooled further by the chiller of the instant invention which utilizes the change in phase, between liquid and gas, of the alternative fuel to cool the incoming air charge.
