Petters Limited were a maker of stationary petrol and diesel engines
Stationary engine
A stationary engine is an engine whose framework does not move. It is normally used not to propel a vehicle but to drive a piece of immobile equipment such as a pump or power tool. They may be powered by steam; or oil-burning or internal combustion engines....

, had a top speed of 12 miles per hour (5.4 m/s) . The vehicle was constructed at the Park Road carriage works of Hill and Boll. It weighed 9 cwt (457 kg) including the 120 lb (55 kg) of the Petter engine with its flywheel and side bars.

A contemporary report said:
The carriage is intended for two persons, with which a speed of ten miles an hour [16 km/h] is obtained on level road. It will mount the hills of the neighbourhood with two persons, but larger power would be used for four persons … The exhaust is, we are informed, quite invisible, and the engine almost noiseless'. The removable handle (indicated in the plan drawing) was used to start the engine 'in the first place, and an arrangement is made so that the handle, when put in position, automatically opens the exhaust valve which closes instantly when, a good impulse being given, the handle is withdrawn and the engine starts … Tube ignition is adopted, and a small heating lamp is used … The engine starts in ten minutes and runs, we are told, without attention.' The larger road wheels of the vehicle were 42 in (1.07 m.) in diameter.

Engines

Failing to achieve the commercial success that they hoped, they adapted the engines for agricultural and industrial use. In 1902 they produced the first agricultural tractor

, powered by a 30 horsepower (22 kW) horizontal oil engine.

The first engines made by Petter were Petter Standard oil engines which were horizontal open crank engines made to very high standards.

With commercial production under way, the family launched a private company called J. B. Petter & Co. Ltd. in 1902.

Around 1903 cheap American imports, including the "Jack of all Trades" manufactured by the Fairbanks Morse Company, threatened the English stationary engine industry, and unlike most companies at the time Petter decided to produce a cheaper engine of their own to combat the threat. This engine was called the Petter Handyman which was sold around 20% lower in price than the 'Petter Standard' and was sold in batches of 50 or more.

From 1920s onwards Petters made two-stroke and four-stroke engines. Such models as the M-type and the A-type were highly successful and were competitors for Lister's

 D-Type.

The last two-stroke design was the "SS", introduced in 1938. It was available in two-cylinder to six-cylinder versions and delivered from 125 to 375 horsepower. The "SS" was described as a "superscavenger" engine. The meaning of this is uncertain but it may indicate that it used the inertial supercharging effect

Petter also manufactured the two-stroke M-type (petrol), the S-type stationary diesel, the A-type, and the A1-type, the only noticeable difference on the previous two being the position of the magneto: the A magneto jutted out, and the A1 magneto was tucked away underneath. The A range was aircooled. Petter also produced another 'handyman, a 'cheap' version of the M-type. Petter went on to make a comprehensive range of air-cooled diesels, such as the PAZ1, AVA range, and the 3.5 hp AA1.

Re-organization

In 1912 the company went public and began engine production in a new factory named the Nautilus Works (after the fire grates that had made James Petter's fortune) in Reckleford.
Its workforce of 500 men produced 1500 engines a year. In 1919 the company bought the Vickers factory in Ipswich and was renamed Vickers Petters Ltd.

In 1937, Petters joined the Associated British Oil Engine Company
