A DEMONSTRATION was given on Pt November 24 at the garage of William Gillespie and Son, Ltd., Paisley, of the Enness gas producer. The vehicles equipped were a Commer 2-ton lorry, a Morris 12 h.p. saloon carrying the plant at the rear, and a Hudson 21.6 h.p. car with the apparatus on a trailer.
These three standardized plants weigh about 4, 24 and n cwt. respectively, and their costs are EDO, £65, and £80. The producer is of the crossdraught type and is designed for Welsh anthracite. Engine suction when running on petrol is used for starting.
After about a mile on the road the engine was found to run smoothly on gas after a small adjustment of the airmixing valve had been made. There is a definite loss of power, however, most noticeable on .gradients, and some loss of flexibility in traffic, but with this system a hand throttle allows the petrol carburetter to be brought into use if more power is required. Petrol and gas can then be used together or separately.
Driven in normal fashion, the vehicle should have a very small petrol consumption, and with anthracite at 4s. per cwt. fuel costs are claimed to be reduced to a third. The producer holds a charge sufficient for 70 to 80 miles' running, and topping-up or cleaning-out and recharging appeared
quite simple operations. There are cleaners which require occasional attention, and a main scrubber which should be cleaned every 1,000 miles. Quite practicable for car use, such a plant woufd seem to have the greatest possibilities for heavier transport between points on the open road.
The plant demonstrated is the product of Neil and Spencer, Ltd., 43, Clapham Crescent, London, S.W.4, but is shortly to be manufactured in Scotland by the Eastern Manufacturing Co., Arbroath.
