SU1333812A1 - Apparatus for comparable tests of air cleaners of i.c.engines - Google Patents

Abstract

The invention improves the accuracy of comparative tests. The dp of this reference and test air cleaners 9 and 12 are made in the form of two sections 6, 7 separated by a partition 5, half of each air cleaner and located in one housing 4. Each section 6.7 is connected to one side through the inlet path 15.16. one group of 2.3 cylinders, and on the other hand - with a common air intake 8. The accuracy of the tests is improved by the fact that they are carried out on the same engine and in the same modes at the same time and at the same time the dust is taken ha / ha Erez common intake 8, which guarantees the identity of its members. This allows the device to be used in both stationary and operational conditions. 1 il. § (P

Description

one

The invention relates to mechanical engineering, primarily to engine building, in particular to devices for testing air cleaners.

The aim of the invention is to improve the accuracy.

The drawing shows a device for comparative testing of air cleaners.

The device contains a U-shaped engine 1 of internal combustion, which has two equal by the number of cylinders of groups 2 and 3. On engine 1 there is a housing 4, divided by a partition 5 into sections 6 and 7, connected to a common air intake 8

Section 6 houses half of the reference air cleaner 9, for example, consisting of a series of IP cyclones constituting the primary cleaning stage and the filter element 11 of the secondary cleaning stage. In section 7, half of the test air cleaner 12 is located, having a different row of cyclones 13 and a fine filter element 4. Section 6 is connected via inlet tract 15 to a group of 2 cylinders, and section 7 via intake tract 16 to a group of 3 cylinders. On the intake tracts 15 and 16 can be installed instrumentation 17 (piezometers, photo cells, etc.)

When the engine is running, the air through the common air intake 8 enters simultaneously into the reference air cleaner 9 and the air cleaner 12 under test, and then into the corresponding group 2 and 3 of the engine j cylinders.

Claims (1)

The cleaning quality of each section with the reference air cleaner 9 and the air cleaner 12 under test and the air flow through each air cleaner are determined using test instruments 17. In addition, the degree of wear of the mating parts of engine 1 is determined. Due to the fact that The engine simultaneously, in the same modes and at the same time, takes in dusty air through a common air intake 8, which guarantees the identity of its composition, increases the accuracy of comparative tests and poses It will use the device both in stationary and in operation. statutory conditions. Invention Formula A device for comparative testing of air cleaners for internal combustion engines containing a reference and test air cleaners and an internal combustion engine having two equal groups of cylinders with an independent intake tract, characterized in that, in order to improve accuracy, the reference and test air cleaners are made in two sections separated by a septum constituting half of each air cleaner and located in the same housing, each section being connected on one side through a corresponding There is an intake tract with only one group of cylinders and, on the other hand, with a common air intake.
