Aqueous hydrogen peroxide system and temporary piping were used to recover LP carbamate ammonium into HP system, thus the problem of liquid entrainment in the vented tail gas from HP scrubber was effectively solved.

This paper uses the portable emission measurement system(PEMS) OEM-2100 to collect the real-time vehicle emission data at intersections as well as on the road,and develops the analysis platform for the emission data based on GIS and corresponding secondary developing tools.

The On-board Emission Measurement System(OEM) is a real-time vehicle emission measuring system for real-world driving and road conditions.

In this paper,the main factor is analyzed that influence the emission of XIALI taxi after turned into bi-fuel vehicle.

The engine performance and emissions are researched.

Reducing exhaust emission from construction machines and vehicles;

The more and more strict limit for diesel exhaust emissions requires to further improve diesel enginetechniques and to apply exhaust after - treatment techniques.

In this paper, the study on exhaust emission from 2-stroke, 4-stroke gasoline engine and diesel engine, burning methanol-gasoline blend fuel and M100 methanol fuel has been reported.

Research of Fuel Properties Effects on Vehicle Exhaust Emissions;

A set of diesel/CNG dual fuel system based on Intel 16-bit single chip microprocessor is researched to solve the problem of city vehicles exhaust emissions.
