It featured a separate oil supply which directly injected oil into the gasoline prior to combustion ( traditionally riders had to pre-mix oil into gasoline together before filling the gas tank on two stroke engines ).

All three were two stroke engines equipped with Crossley's system of exhaust pulse pressure charging whereby surplus air in the exhaust manifold was forced back into the cylinder by the exhaust pulse from a neighbouring cylinder.
43.
It is started using a pedal start mechanism where the user provides the force needed to start the 49.9 cc two stroke engine, or can be ridden like a bicycle when the engine is disengaged.

The actual gas leaving the pipe during a particular cycle was created two or three cycles earlier . ( This is why exhaust gas sampling on two stroke engines is done with a special valve right in the exhaust port.

Engines fitted include the 48 kW ( 64 hp ) Rotax 532, the similar 48 kW ( 64 hp ) Rotax 582 two cylinder two stroke engine and the 64 kW ( 85 hp ) Jabiru 2200 flat four.

The forkless front suspension was criticised as leading to " non-harmonic and wobbly dynamics at lower speeds . " Some critics complained about the noise level of the large water cooled two stroke engine, which had a catalyst:

In 1909 he designed a two-stroke 3.3-litre engine, for his cousin Ralph Ricardo, who had established a small car manufacturing company, " Two Stroke Engine Company ", at Shoreham-by-Sea.

V . T . S . were manufactured by The Valveless Two Stroke Engine Company Ltd . of Birmingham, England, and sold exclusively to Sun Cycle & Fittings Co . Ltd . ( whose frames were used on Waratah motorcycles ).

In 1992 a number of prototype cars were produced by Ford fitted with direct injection two stroke engines produced by the Orbital Engine Corporation of Australia, with full-scale production anticipated by Ford in " two to three years time ".
50.
The freewheel was required in the normal ( non oil pump engines ) SAAB two stroke engines but not in the Sonett since it had an automatic oiling system fed from a supply tank that obviated the need to add oil to the gas.
