Malfaunction and causes

Remedy

1

Gas system malfunctions:
(1)Low gas pressure and gas supplying shortage
(2)Low quality gas and low efficiency content
(3)There is crack for gas mixer seal
(4)Gas inlet pipe block

Increase gas pressure

Increase gas inlet capacity

Change the seal

Clean

2

Malfunction of gas inlet and outlet system: higher exhuast temperature and worse exhaust gas color than normal situation
(1)Air filter is blocked
(2)Exhaust pipe is blocked or too long, the radius of turn pipe is too small and tow much elbows.

Note: Use hand to turn engine and make sure the cylinder is in the free situation and check if there is oil block for gas inlet pipe.

Dismantle and clean, change it if it is necessary

Clean the carbon deposit in exhaust pipe, install exhuast pipe again, the elbows can not much than 3 units and to make sure there is enough exhuast outlet space

3

Over-heat for engine and ambient environment. The oil and coolant temperature is too high and the exhuast gas temperature is increased greatly.

Check the radiator and cooler, clean water deposit, check some pipes if their radius is too small. If the ambient temperature is too high, users should improve the ventilation system and add some cooling measures.

4

Cylinder malfunction:
The single cylinder power is not enuogh and decreased one by one. Besides, there is gas leaking and black smoke for gas inlet pipe, and with abnormal knocking, etc.

(1) Cylinder gasket is leaking

(2) Inlet and outlet gas valve leaking

(3) Valve spring is damaged

(4) Wrong valve clearance

(5) Crankcase is fractured

Note: Dismantle ignition spark to let  cylinder have good ventilation, discharge coolant; Tighten stud nut and change cylinder gasket according to required torque. Scrape joint surface if necessary

(1)Change cylinder cover gasket
(2)Change gas inlet and outlet pipe
(3)Change the damaged spring
(4)Adjust valve clearance
(5)Change crankcase

5

The piston is blocked; valve rod is seized and so cause the deficiency of cylinder compression pressure.

Change the piston equipments or cylinders; Find out the reason of block (If its because of not enough lubrication and cooling, or over-load, etc) and adjust it.
