Internal combustion engine |
摘要 |
An internal combustion engine has a vacuum spark timing control system to advance and retard the spark in which the spark is kept retarded until a predetermined time passes after the engine speed exceeds a predetermined reference engine speed that demarcates the high engine speed range from the low engine speed range operations. During the low engine speed range operation the spark is retarded, while during the high engine speed range operation, the spark is advanced.
