摘要：An internal combustion engine (1) includes a variable compression ratiomechanism (2), and a common rail type fuel injection device using a high pressure fuelpump (46) which is mechanically driven. A fuel pressure P within the common rail (45) isread (step 1). When the fuel pressure P exceeds an upper limit fuel pressure Pmax (step4), an abnormal increase of the fuel pressure P is judged. A target compression ratio bythe variable compression ratio mechanism is set to a minimum compression ratio E min(step 6). With this, a rotation variation of a crank shaft (21) becomes small. A tensionvariation of a chain (43) is relieved. A reduction of durability of the chain (43) issuppressed.
