Abstract

The invention relates to a measurement technique, namely a compressometer, for determining the pressure of gases in the cylinders of internal combustion engines. The aim of the invention is to increase the reliability and versatility of the application. Compressometer is connected to the injector socket in the engine using elements installed in the annular grooves 3 of adapter 2. Gas enters through the channels of tip 6 and adapter 2 to inlet valve 9 installed at the entrance to the cavity of housing 1, at the outlet of which exhaust valve 7 is installed and pressure gauge 10. Both valves are preloaded with one spring 8, which increases the preload of one valve when the other is open. 3 il.

The invention relates to a measurement technique and can be used in control equipment for testing internal combustion engines to determine the magnitude of the gas pressure in the engine cylinders.

The aim of the invention is to improve the reliability of operation and versatility of use.

FIG. 1 shows the device, a general view; in fig. 2 and 3 - connecting elements installed in the annular grooves of the adapter.

Compressometer contains a body of 1 s. adapter 2, on which annular grooves 3 are made, in which supporting elements are installed, made either as washers 4, or as flag 5, depending on the type of engine, by means of which the compressor is attached to the test cylinder. The lower part of adapter 2 is connected with a replaceable tip 6. In case 1, a discharge valve 7 protruding to the outside is installed, connected by means of Prulsine 8 to an inlet valve 9, which allows fixing maximum readings of pressure gauge 0.

Compressometer works as follows.

Remove the injector pump or the injector of the cylinder to be tested and install a Compressometer instead. Depending on the type of engine, either washer 4 or flange 5 is inserted into one of the grooves 3 made on adapter 2. Then the crankshaft is cranked, creating pressure. Compressed cart

the spirit enters through the tip inlet and, acting on the rubber ring of valve 9, lifts it. The air enters the pressure gauge 10, and the inlet valve 7, by the action of the spring 8, blocks the access of compressed air to the exhaust hole 5. The pressure value at the end of the compression stroke is determined by the scale of the pressure gauge 10. The pressure gauge is reset by pressing the valve 7, which moves down and allows access to compressed air at outlet S.
