摘要： A piston for a four valve direct injection diesel engine defines a combustion chamber comprising a recess (10) in the piston crown, which is rotationally symmetrical about the axis of the piston in axial cross-section and is defined by a base and a side wall. A generally conical projection (5) is upstanding from the base. The recess (10) includes a lower toroidal portion (8) and an upper portion (10), whose diameter progressively increases towards the piston crown. The upper and lower portions of the recess are separated by an annular, arcuate lip (12) extending into the recess. The included angle of the conical projection (5) is between 104° and 108°, the maximum depth of the recess (10) is between 13% and 22% of the diameter of the piston, the conical projection (5) merges with the base of the recess along a circular line whose diameter is between 38% and 44% of the diameter of the piston, the diameter of the lip (12) is between 54% and 59% of the diameter of the piston, the line of minimum diameter of the lip (12) is situated at a distance between 5% and 10% of the diameter of the piston from the plane of the piston crown and the diameter of the upper portion (10) of the recess increases from 54% to 59% of the diameter of the piston at the line of minimum diameter of the lip to between 72% and 76% of the diameter of the piston at the line where the side wall of the recess intersects the plane of the piston crown.

摘要： A diesel engine comprises a plurality of cylinders (2), an inlet duct (4), an exhaust duct (6), a turbocharger (8, 10) and a supercharger (14), the turbocharger being of variable output type and including a turbine (8) in the exhaust duct (6) and a supercharger (14) being of variable output type and situated in the inlet duct (4) between the compressor wheel (10) and the cylinders and being electrically driven or mechanically driven by the engine. The engine also includes a first sensor (25) arranged to produce a signal indicative of the speed of the engine, a second sensor (27) arranged to produce a signal indicative of the load to which the engine is subjected and a third sensor (26) arranged to produce a signal indicative of the pressure in the inlet duct (4) downstream of the supercharger (14). The sensors (25, 27, 26) are connected to a controller (29) which is also connected to the turbocharger and the supercharger and is arranged to vary their output independently. The controller (29) is programmed to determine the desired value of the pressure in the inlet duct (4) downstream of the supercharger (14) and to compare this with the actual value of the pressure and, in the event of there being a difference, to adjust the output of the supercharger and/or turbocharger until there is substantially no difference. The controller (29) is also programmed, if a higher pressure is required in the inlet duct (4), to preferentially increase the output of the turbocharger, subject to the pressure in the exhaust duct (6) not exceeding a predetermined value and, if a lower pressure is required in the inlet duct, preferentially to decrease the output of the supercharger.

摘要： An in-cylinder pressure sensor obtains a high resolution pressure curve for each cylinder cycle allowing the various data to be derived for improved monitoring and control of operation of the engine. A more accurate measure of work done by the engine is obtained allowing more accurate estimation of the vehicle torque and hence real torque control. In addition engine losses can be more accurately calculated and the estimates corrected yet further by obtaining an accurate top dead centre position for the engine cylinders.
