4.5 Experimental research of system of heating of car IZH-2126
Trial were spent in control of special trials of general department of Open Society "Autovases".
Definition of an overall performance of system of heating of salon, dusting and heating wind and side glasses of the car at low temperatures of air is carried out on following points:
Trials of a system effectiveness of heating of salon.
Trials of system of heating and ventilation on volume of passed air.
S-103 «The Standard of safety of the USA on windscreen defrosting».
Definition of adjusting performance of a heater.
The tested car is completed by own heater,
Having the crane and zaslonku controls of a heater, and also zaslonku, overlapping air exit in feet. The ventilator of a heater 2108-8101091 (same as on VAZ-2108) it is established immediately in a box vozduhopritoka in podkapotnom space. In a box vozduhopritoka there is a valve for water plum.
Trials were spent in the refrigerating chamber at air temperature-20...-33°С.
Trials on point 3 were spent in OAKI at the stand of trials of heaters.
By preparation of the car for trials operations by definition of productivity of system of heating and ventilation have been spent, tightness of a body is defined. Samplings of speeds of air on an exit from deflektorov a dusting of a zone of feet of the driver and the forward passenger have been thus made. Results of trials are presented on fig. 4.15 and in table 4.6.

Speed of increase of temperatures is displayed on fig. 4.7
The low temperature of air in a zone of feet of the back right passenger speaks that the stream of air which is going out an airline of heating of feet of the back passenger hits in a strip of a sled of the right forward sitting and does not get immediately to a zone of feet of the back passenger.

12. During trials following deficiencies of system of heating are marked:
The short cable of a drive zaslonki «in a foot» - not completely overlaps air stream in the lower part of salon.
Missing of warm air in a zone of feet of the back right passenger from an airline of heating of feet of back passengers.
Arrangement deflektorov exhaust ventilation of salon with
With back-pressure valves on an upholstery of back doors does not ensure tightness of a body as at the lowered windshields will be podsasyvatsja air from an internal cavity of doors through holes of an upholstery of back doors.
Outputs under the head
Results of experimental researches have displayed, that the system of heating of car IZH-2126 ensures comfortable limits of temperatures of air in salon on a place of the driver and the forward passenger at air temperature-37 ° With and above, and admissible (comprehensible) limits of temperatures at-42 ° With.
The system of a dusting and heating wind and side windshields corresponds to requirements of the standard of safety of USA S-103 on defrosting of glasses.
