This paper summarized the principle of fuel supply of common rail diesel injection system,and take Cummins ISBe150 diesel equipped with BOSCH 4 cylinders common rail diesel injection system for example,apply conventional fuel consumption measuring method of diesel vehicle to measure the fuel consumption,and present the weight-measuring method of measuring cup and tube,the test method of dual fuel consumption device and improved conventional measuring method, the principle of improved conventional measuring method is mainly introduced.
It is indicated that speeding up the study and development of natural gas automobiles is imperahve,and two problems must be solved: one is refitting the existing gasoline/diesel automobiles,and the other is building up a network of gas filling stations.
This paper presents a suitable area for the annual reduction factor of highway tunnel qvi, which decreases progressively by 1%～2%, according to the domestic and international environmental protection requirements and analyses and researches on the composition of automobile smoke emission, variation of the qvi recommended by PIARC, variation of the limited values for PM emission of diesel automobiles and the scientific and technological progress of our country etc. .
By virtue of CATARC's testing abilities and advanced measurement instruments such as ELPI for PM testing and OBS-2200 for gaseous pollutants, we designed rigorous experiment scheme, carried on bench test and on-road emission test, discussed the challenge brought by the upgrading regulation and the influence of fuel and SCR, and researched emission characteristics of diesel vehicles on real road conditions.
Profile of PAHs in the Diesel Vehicle Exhaust in Delhi
Six source factors (gasoline vehicle exhaust, diesel vehicle exhaust+residential heating, paint production/application, degreasing, dry cleaning, and an undefined source) were extracted from the samples collected in the urban site.
Three source factors (gasoline vehicle exhaust, diesel vehicle exhaust, and paint production/application) were identified for the suburban site.
Relative Contribution of Various Diesel Vehicle Classes to the Thessaloniki Urban Air Pollution
Interaction of some pollutant oxides on durability of silicon carbide as a material for diesel vehicle filters
