DIRECT-INJECTION INTERNAL COMBUSTION ENGINE AND METHOD OF CONTROLLING THE SAME |
摘要 |
Tn a direct-injection internal combustion engine (1-1), a variable intake valve (41), of which valve timing can be varied, is used as an air intake valve through which an air intake path (5) and a combustion chamber (A) communicate with each other. The direct-injection internal combustion engine (1-1) includes: a variable-intake- valve control section (75) that controls the valve timing of the valuable intake valve (41); and an intake-air temperature acquisition section (74) that acquires a temperature of the intake air introduced into the combustion chamber (A). When the fuel is injected into the combustion chamber (A) via a fuel injection valve (21) during the compression stroke or the expansion stroke, if the acquired intake-air temperature is low, the closing timing of the variable intake valve (41) is advanced, so that the actual compression ratio is increased. |
