We make bench scale test to compare the fuel oil saving efficiency using three marketable different kinds of energy saving additives and find out that the absolute value of fuel oil saving efficiency is not less than 5% even though at low load while the relative value is big,about from two to seven times between different kinds of energy saving additives.

Methods Using fuel additive; Maintaining the construction machines regularly;Reducing exhaust fumes in neutral position of the engines;The air vent is designed to up the bank by 8～10?m; Keeping the air conduct sealed and ventilation work effectively.

In order to investigate the influence of a new multi-effect fuel additive (code-named MAZ) on the combustion and exhaust property of gasoline engine, the function and basic working principle of fuel additives were introduced, and under the same work conditions, a series of full-load and part-load experiments were performed on an engine test-bench using gasoline with or without the addition of MAZ.

Research on regeneration characteristic of diesel particulate trap using fuel additive is conducted on light duty diesel engine.

Diesel engines can produce higher soot emissions due to its diffusion combustion mode and small amounts of fuel additives can improve such process and thereby reduce emissions.

Based on a series of experiments and tests of MAZ multi-effect oil additive,the technologic feasibility of the new multi-effect oil additive’s popularization and application was analyzed,and its economic and social effect was discussed.

Based on the composition and operation principle of the nitryl fuel additive(MAZ),the influences of the gasoline with the MAZ additive on the oil consumption and exhaust of a car are researched.

This article makes an analysis on the combusting test of the biochemical fuel additive on oil boiler.
