摘要： A collecting exhaust port 18 provided in a cylinder head 12 is comprised of exhaust port sections 46 extending from exhaust valve bores 35 in cylinders 14, and an exhaust collecting section 47 in which the exhaust port sections 46 are collected. The cylinder head 12 includes a protrusion 49 projecting in an arch shape outside a side wall 111 of a cylinder block 11. The exhaust collecting section 47 of the collecting exhaust port 18 directly faces an inner surface of a side wall 12 of the protrusion 49. Water jackets J2 and J3 for cooling the protrusion 49 are provided in upper and lower surfaces of the protrusion 49 having the collecting exhaust port 18 defined therein. The water jackets J2 and J3 are not provided between the side wall 121 of the protrusion 49 and the exhaust collecting section 47. Thus, the compact cylinder head 12 having the collecting exhaust port 18 integrally provided therein can be formed, while avoiding the complication of the structure of a core.

摘要： A valve control system controls the valve lift characteristic of at least one set of a set of inlet valves and a set of exhaust valves of an internal combustion engine installed in an automotive vehicle having driving wheels. When the engine is in a specific engine operating region, changeover of the valve lift characteristic is inhibited even when an excessive slip state of the driving wheel(s) is detected, whereas changeover of the valve lift characteristic is permitted when the engine is in other specific operating regions which are defined by the engine rotational speed and the engine load. Restoration of the changed valve lift characteristic to one selected before the change is retarded when the excessive slip state of the driving wheel(s) is eliminated. The engine output is reduced when the valve lift characteristic is restored.

摘要： An oil level sensor for detecting an oil level is arranged in an engine oil pan. The oil level sensor includes a mounting section and a sensing section. An air hole is formed at an upper end of a cover member of the sensing section. The air hole is surrounded by a tubular portion of a shield member attached to a baffle plate of the oil pan. Therefore, any splashed engine oil in the oil pan is restricted from entering the cover member of the sensing section through the air hole. Also, a clearance (α) for venting air is formed between the tubular portion and the baffle plate.

摘要： An ignition timing control system for an internal combustion engine is operable to detect knocking occurring in the engine, determine basic ignition timing based upon operating conditions of the engine, correct the basic ignition timing by a correction value which is determined in response to an output from a knocking sensor, and inhibit correction of the correction value toward an advanced side with respect to at least one predetermined value in a timing retarding direction which is determined based upon operating conditions of the engine, when the correction value is greater than the at least one predetermined value. The correction value is initialized to a value based upon the difference between the correction value and the at least one predetermined value when the correction value exceeds the at least one predetermine value.

摘要： A system for controlling ignition timing of a vehicle internal combustion engine, in which a plurality of sets of ignition timing control characteristics are established in response to the octane numbers of different kinds of fuel which may intentionally or unintentionally be used in the vehicle. The system infers the octane number of the fuel being used from the occurrence state of knock and selects the set of control characteristics corresponding to the selected fuel octane number, whereafter it determines the ignition timing based on the selected set of control characteristics. The system overcomes the problem of unnecessarily reduced torque occurring when the set of characteristics for low octane number fuel is misselected when the vehicle is running on high octane number fuel, as may happen particularly at the time of engine cold start, since during warmup the engine is apt to produce mechanical noise resulting in spurious knock detection. Upon completion of engine warmup, the system concerned advances the ignition timing by unit amounts if no knock occurs in the course of the advancement, forcibly shifts from retarded to advanced characteristics.

摘要： A system for controlling an ignition timing of an internal combustion engine, in which an ignition timing advancing correction amount is determined based on at least the detected engine coolant temperature, and it is determined whether the engine is under a predetermined cold starting condition. When the result is affirmative, the ignition timing is advanced beyond the MBT. This arrangement is based on the inventors finding that the gas temperature rises at the combustion stroke, but drops little after the expansion stroke. With this, the increased fuel amount for compensating the engine output loss caused by ignition timing advancement can effectively be utilized to heat the engine coolant, thereby facilitating and improving the engine warm-up.

摘要： A system for controlling ignition timing of a vehicle internal combustion engine, in which a plurality of sets of ignition timing control characteristics are established in response to the octane numbers of different kinds of fuel which may intentionally or unintentionally be used in the vehicle. The system infers the octane number of the fuel being used from the occurrence state of knock and selects the set of control characteristics corresponding to the selected fuel octane number, whereafter it determines the ignition timing based on the selected set of control characteristics. The system overcomes the disadvantages of the conventional system, namely that when the set of characteristics for low octane number fuel is misselected when the vehicle is running on high octane number fuel, resulting in unnecessary reduction of output torque, either the conditions under which it is possible to forcibly shift to the set of conditions for high octane number fuel are limited to special ones, specifically to low engine speed operating condition, or if not so limited, the knock which occurs when the forcible shift is carried out causes a shift in the opposite direction, whereby the control experiences undesirable hunting.
