Vehicles


The components of the wood gas equipment are quite big and when installed on a vehicle they often reduce visibility. The performance of the vehicle is not as good as with a gasoline engine and the driver must adjust the system every now and then. Using and maintaining the equipment is not without risk. Safety aspects must be noted. The users must be trained well to use the equipment. Special attention must be paid to the risk of poisoning.

In general the installation on vehicles of different types can be made in the following way:

The gas generator must be installed firmly in vertical position. Other parts and the load must be thermally insulated from the generator. The temperature of the outer surface of the generator can be up to 300°C. The intake air for the generator must be taken from the hottest possible place for example in the vicinity of the exhaust manifold. This increases the heating power of the gas and improves fuel drying. The starting gas output pipe must be aligned so that the gas can not enter the cabin.

Spark trap
If the spark trap (cyclone) is not thermally insulated the temperature of the outer surface can raise to 400°C. When the spark trap is properly insulated there is no risk for a fire.
 
Filter
When the filter is thermally insulated its outer surface is not hot. The filter must be secured firmly. An important point to notice in design and installation is easy maintenance: easy removal of ash and easy cleaning of the filter element. The maximum temperature of the gas entering the filter is 400°C.
 
Cooler
The cooler is designed to match the dimensions of the vehicle's own radiator and installed as close to it as possible to make sure that the air flow generated by the radiator fan ensures good cooling when used stationary. If the cooler can not be installed in the front of the radiator a separate cooling fan is needed. In a car the air flow generated by the driving speed is sufficient to provide proper cooling. The temperature of the gas entering the cooler is about 350°C and the temperature of the gas leaving the cooler is about 35°C.
 
Distribution reservoir
The distribution reservoir must be installed between the cooler and the mixer. The proper volume for it is 10 liter and it must be filled with rolled expanded metal. The distribution reservoir must be equipped with a draining plug or tap to make draining the condensed liquids easy.
 
Mixer
The mixer is installed as close to the inlet manifold as possible. The mixer mixes the fresh air and carbon monoxide. The mixture goes into the engine.
 
Pipes
The pipes must be as short and straight as possible. Especially curves bending downwards must be avoided. The pipes must be gas tight and firm enough to withstand the suction, heat and vibration. The pipes must be spacious to reduce the suction resistance. The temperature of the gas flowing in the pipes varies in the range of 30 - 450°C.
 
Control levers
Operating the control flaps for the mixture and power is best done with levers and bars. The controls must be placed to be easily accessible in the cabin.
