Control device for internal combustion engine


The invention relates to a control device for an internal combustion engine using the center-of-gravity position of a heat generation rate for combustion control. This control device controls the center-of-gravity position of a heat generation rate to correspond to a reference position in a case where an engine cooling water temperature is equal to or higher than a reference cooling water temperature and controls the center-of-gravity position of a heat generation rate to correspond to a crank angle further on an advance side than the reference position in a case where the engine cooling water temperature is lower than the reference cooling water temperature..

Fuel injection control system of internal combustion engine


A fuel injection control system of an internal combustion engine driven by an alcohol blended fuel includes a controller that controls the amount of the fuel injected from a fuel injection valve. The controller performs injection amount control after start of cranking, when an alcohol concentration of the alcohol blended fuel is higher than a predetermined concentration, so that the amount of the alcohol blended fuel injected from the fuel injection valve in each fuel injection is controlled to be smaller than an amount of the fuel with which an air-fuel ratio becomes a combustible air-fuel ratio, until an initial explosion occurs..

Control device for internal combustion engine


An engine ecu 70 sets a combustion parameter (main injection timing, pilot injection timing, fuel injection pressure, turbocharging pressure, or the like) such that a center-of-gravity position of a heat generation rate becomes a constant target crank angle regardless of a load of an engine 10. In addition, the ecu 70 estimates the center-of-gravity position of a heat generation rate based on an output of an in-cylinder pressure sensor 64 and feedback-controls the combustion parameter such that the estimated center-of-gravity position of a heat generation rate becomes equal to the target crank angle..

Windstorm damper device


An damping device for an exit device that is configured to resist high velocity movement a latch assembly relative to a baseplate assembly. Pivotal displacement of a bell crank during typical operation of the exit device may cause a protrusion of the bell crank to exert a pulling force on control linkage element that is coupled to a connection link of a latch assembly and a spring damper element of the damper device, thereby operating the latch assembly while also generally by-passing the damping effect of the damping device.

Variably expanding chain transmission


A bicycle transmission allows a bicycle operator to change the radius of a pedal crank's transmission gear as sliding gear segments, radially arranged on a base ring assembly, vary their relative radial position from the center of the base plate. These gear segments slide in and out to change the effective radius of the gear.
