| R.R. 235A (100TJ) (S.H 798 10-12-20) G. {Mr Griffiths - Chief Accountant / Mr Gnapp} 2947 R. {Sir Henry Royce} Anderson Consulting Engineer. 54 Church Street, EGREMONT. LIVERPOOL. Jan 27th, 1921. Dear Sir, Re Patent Carb: Jector - Vacuum Silencer. I sent your letter on to Mr Hunter of Blackpool to answer you direct re above. Have you heard from him yet? if not, you might test your latest car with a run to Blackpool some week-end. Then you could test on 40 H.P. Iris car, which is fitted with the Vacuum Gauge on the Dash, but make a fixed appointment first. Mr Hunter's private address is - 13 London Road Blackpool. Also see what extra power we can get on a 2 stroke motor bike. This vacuum makes possible the engine of the future, 4 cylinder, valveless, two-stroke engine working without any crankcase compression or choked exhaust. This engine gives the same number of explosions and power as an 8 cylinder four-stroke. Equal turning movement, much lighter, and cheaper to make. We can drawn the petrol into the carburetter with the petrol tank 6 feet below the top of the bonnet just to shew the power of the Vacuum. I would come and work on this patent engine until perfect at £4 per week. Could you kindly inform me what is the highest compression ever used on a petrol aeroplane or car engine, or possible Diesel work at 500 lbs compression - Temperature 1600 Fah: Boyles Law (100 lbs or what) Yours faithfully, Rob. Anderson. | ||
