1. INTRODUCTION

From on the object to take proceeding against principals trial are: from adjust, from taking over, from inspection testing and control, specials trials, standard and from investigation.

The trials from investigation is make with object from has to work out different problems referring to thermal process, changing from gas, to working mechanism, user materials from construction, and from exploitation or from strength indication stabilization, in seeing engines perfecting existing and new engines realization. The equipment for to try are constituted by: sample stall equipped with apparatus and the feeding devices with fuel and coping water, the pipeline of the gases evacuation, apparatus and devices for the measurement's effectuation. The equipment for to try of the engine with fuel injection is made by: foundation with a plate and a frame, on wick it is fixed the equipment for testing; the engine supply system with consumption and the devices wick to allow -the determination of the consummated combustible quantity; the engine's starting system; the evacuation system of the burned gases and of the damping of the sound; the system for of the oil, air's delft and water's delft consumption; apparatus for the measure of temperature of pressure etc.; the equipment for to broke, wick can be either hydraulic or electric; (Negrea, & Sandu, 2000).

2. THE TESTING PRESENTATION

At the engines stall have been brought in order to try a Mono-Motronic (Grunwald, 1980), injection system engine type 106-20 equipped with carburetor 28/30 DCI. The injection's and lighting map drawings used at the engine with fuel injection expert meted by the author constitute some networks of characteristics with are put in the memory under the numerical form into an electronic module. They do not alter net much on the whole duration of the engine's work-ink. The electronic variation of the advance at the lighting has two important advantages the relative information to the revolution speed is directly taken from the shaft engine thank to in inductive sound with a highly precision of measure and the using of a map drawing allows to obtain adjustment of the advances angle at the lighting. The testing have carried on retiring to the followings the engine's running in; the determination of the dynamic and of consumption's .At the engines stall have been brought in order to try a Mono-Motronic injection system engine type 106-10 equipped with carburetor 28/30 DCI.

The injection's and lighting map drawings used at the engine with fuel injection expert meted by the author constitute some networks of characteristics with are put in the memory under the numerical form into an electronic module. They do not alter net much on the whole duration of the engine's work-ink. The electronic variation of the advance at the lighting has two important advantages the relative information to the revolution speed is directly taken from the shaft engine thank to in inductive sound with a highly precision of measure and the using of a map drawing allows to obtain adjustment of the advances angle at the lighting (Bajaga, 2000). The testing have carried on retiring to the followings the engine's running in; the determination of the dynamic and of consumption's performances according to SR ISO 1585/1998 and the carburetor variant; the determination of the STAS 6635/87 and of the combustible consumption's performance according to; in the fuel injection's variant; the comparison of the obtained results in the two equipment variant presented in the figures 1,2, and 3 (Blaga, 2000), (Blaga, 2005).

3. CONCLUSION

For the equipped engine's with the model supposed by the author, have been raised up on the engine stall, the main cartograms for the injection's times, at totally and partially task (Grunwald, 1980) and the enrichment's coefficient at the totally task which are presented in the figure no.4 (Blaga, 2000).

To make a comparison betwen characteristic's at partially task. Engine's type 106-10 with carburetor 28/30DCI and characteristic's at partially task. Engine's type 106-10 with engine injection is obvious the superiority of last type, technic, economic and environmental protection.
