摘要： PURPOSE:To make an insertion hole for a spark plug installable in position between two exhaust ports in an inclinatory manner, by forming these two exhaust ports a cylinder head so as to be bulged to both sides in the vicinity of an opening part at the combustion chamber side. CONSTITUTION:In order to avoid any interference with an insertion hole 36, two exhaust ports 18 and 18 are bulged to both sides so as to be mutually separated from opening parts 18a and 18a at the combustion chamber side. And, the insertion hole 36 is made to pass through between the bulged parts 18c and 18c, while downstream parts 18d and 18d are made to come closer again from a spot beyond the insertion hole 36 whereby a plane surface form in these exhaust ports 18 and 18 is made so as to become almost parallelism as a whole. With this constitution, the insertion hole 36 for a spark plug is installable in position between these two exhaust ports 18 and 18 in an inclinatory manner, thus such a four-valve on-overhead cam shaft engine as being simplified in structure and excellent in combustibility and serviceability is secured.

摘要： PROBLEM TO BE SOLVED: To improve ignitability by the mutual interference effect between fuel atomization in warm starting, while maintaining ignitability in cold starting. SOLUTION: This spark-ignition direct-injection engine has a fuel injection timing control means for setting the fuel injection timing to a compression stroke in warm starting, and to an intake stroke in cold starting, by pointing the injection direction of fuel injected from a fuel injection valve 18, to the electrode vicinity of a spark plug 16, and a fuel pressure adjusting means for adjusting pressure of fuel to fuel pressure higher than cold starting in warm starting.

摘要： PROBLEM TO BE SOLVED: To prevent knocking and improve engine output without executing substantial ignition retard by attenuating tumble flow generated by a protruded part formed in a piston top part when the intake amount is high, if strong tumble flow is generated by passing through a bend in an intake passage the intake partially is throttled by closing a valve element arranged in the intake passage when the intake amount is low. SOLUTION: When the intake amount is low, a flow control valve 20 arranged in the intake passage is closed. By so doing, the intake partially throttled passes through a bend 5e to generate a strong tumble flow f1. When the intake amount is high, the flow control valve 20 is opened. However, a strong tumble flow f1 is generated by the bend 5e. The tumble flow f1 is attenuated by the protruded part 3b formed in the piston top part 3a. COPYRIGHT: (C)2005,JPO&NCIPI
