摘要： A method of controlling a fuel injector comprises measuring a pressure in a cylinder of an engine with a pressure sensor and determining at least one of a crank angle and a crank speed with a crank sensor. The method also comprises calculating a net indicated mean effective pressure of the cylinder from the measured value of the pressure sensor and the determined value of the crank sensor. Also, the method comprises adjusting a fueling parameter of a fuel injector for the cylinder in response to the difference between the calculated net indicated mean effective pressure and a reference mean effective pressure indicates a change in power of the engine. Alternatively, the method may adjust the fueling parameter based on a power feedback signal for the engine.

摘要： A cylinder liner and piston configuration for an internal combustion engine includes features for improving the cooling of the piston. Specific ratios and dimensions are included to optimize the features of the cylinder liner and piston. Also included are unique piston features that assist in achieving some of the specified dimensions and ratios.
