Particulate Matter Emissions from Direct Injection Gasoline Passenger Car

直噴ガソリン乗用車の粒子状物質排出特性

A study has been carried out to measure the particle mass, size, and emissions from the latest direct injection gasoline passenger car equipped with idling reduction under urban driving cycles. The test vehicle emitted ultra-fine particles which have a concentration peak in 70 to 80 nm diameter. The particle mass emissions were lower than the Japanese PM limit for diesel passenger cars, however particle number emissions measured by EEPS (Engine Exhaust Particle Sizer) exceeded the EURO 5b and 6 limit for diesel passenger cars. The idling reduction was effective in carbon dioxide (CO2) reduction; however it was shown that idling reduction enhances the particulate mass emission at the acceleration just after the engine start. 最新の筒内直接噴射ガソリンエンジンから排出される粒子状物質について、都市内実走行モード等により、その排出重量、排出個数、粒径分布、炭素成分などを測定した。排出重量は、最新のディーゼル乗用車の規制値以下であったが、個数排出量は、欧州で定められているディーゼル車の排出規制値を上回る結果となった。
