E.N.V. Aero-engine type D (40hp), V8 cylinder, (incomplete), E. N. V. Motor Syndicate Limited, Willesden, Middlesex, England, 1910-1911. The engine’s cast-iron cylinders machined inside and out, have electrically deposited copper water jackets. The crankshaft is supported in six ball-bearings, with a double thrust race at the propeller end to take thrust in both directions. The side valves are operated by a hollow camshaft working through hardened steel balls at the bottom of each tappet. Lubrication is forced fed by a pump actuated by an eccentric on the crankshaft. Used in 1910, by Harold Hume Piffard, when he flew his flies 'Humming Bird' aircraft from Shoreham Airport, Shoreham, Sussex, England.
