gas be watched!
In the June issue we talked about the structure and operation of domestic LPG equipment designed for passenger cars for personal use.
Since its operation has a number of features, it was decided to bring this subject to the Club. It will continue the already familiar to readers Ph.D. VA Luksha (NAMI).
Let's start with the first engine starting operation. In the warm season, he did not present any difficulties. As for the winter, it must be borne in mind start a cold engine on a gaseous fuel is possible at temperature up to minus 5 or minus 10 C. At lower engine it is recommended to start up on petrol.
First of all, you must open the feed valve cylinder valve, set the switch to position the fuel gas. Then press the 1 button for 2 seconds (on the switch) starter solenoid, choke cover and turn the starter. If the engine is not earned in the first 1 2 seconds, lightly cover the choke at the moment when the starter. When the engine is warm, start-up valve can not be included.
Idle speed is recommended to regulate the gas in that order. Start up the engine on petrol and progreem it. Open the feed valve on the tank. Loosen the adjustment screws tee-dispenser (it is placed before the mixer) for 2 2.5 turns from the position when it is fully closed. Set the high speed of the crankshaft can be put forward for the control handle to choke out. Now transfer the fuel switch in the neutral position. In this case, both solenoid valves (for gas and gasoline) are closed and gasoline is consumed from the float chamber. At the first outage set the switch to gas. If the engine runs on gas, gradually move in choke control lever, reducing the speed and controlling the stability of the engine. As soon as the cuts, do not let the engine stall and achieve its stable operation at minimum speed by turning the screw to adjust the output pressure reducer in one direction or another. Before adjusting screw is recommended to turn out the idle, located in the housing system idle (right hand), half a turn from the position which corresponds to a complete closure. If you then fail to achieve stable operation at minimum speed with a screw adjustment of outlet pressure, tighten the screw Idle to 1/8 turn and repeat the adjustment.
The position of the metering screw tee pick up in traffic. Wrapping the screw feed gas into the primary chamber to the carburetor 1/4 turn, check the resistance of the engine at constant speed of 10 15 km / h in first gear, 20 25 km / h on the second and 40 50 km / h on the third. If the dips and jerks the car there, wrap the screw-tee dispenser for another quarter turn and so on. Once under these regimes car started jerking motion, turns the screw on the fourth turn.
Position of the screw feed into the secondary chamber of the conditions we select the best dynamic acceleration from 30 to 60 km / h in third gear. The screw turns up until we reach the smallest starting time. Check the correct adjustments can be overclocked to a direct transfer from a speed of 40 50 km / h In making the choke lever, pay attention to changes in the intensity of acceleration. If it grows, we must also turn the screw feed into the secondary chamber, while reducing it can be wrapped on the fourth turn. After installing the screw feeder tee-check and if necessary adjust the idle speed.
