The original AEC Monarch was built from 1931 to 1939 at AEC's Southall works. The first version had payload of 7 tons (increased to 7⁄ tons from 1933) and was fitted with either an 85 hp (63 kW) four-cylinder 5.1-litre diesel engine or an 80 hp four-cylinder 5.1-litre petrol engine.

Nov 9, 2013 · So instead of the normal 7.7 litre diesel engine, it has a 7.4 litre A193 overhead cam petrol engine, complete with autovac on the front panel. In addition to the petrol mods, it is also completely 12v, rather than the normal split system on a standard Matador.

The AEC Matador was a heavy 4×4 truck and medium artillery tractor built by the Associated Equipment Company for British and Commonwealth forces during World War II.

The AEC Renown was the name given to three distinct forward control bus chassis manufactured by the Associated Equipment Company (AEC) at different periods between 1925 and 1967. All were of the front-engine, rear-wheel-drive layout. The first and third types had two axles, the second had three.

In 1930 AEC introduced its first diesel engine and began the sequence of trucks with ‘M’ names: Mercury, Monarch, Majestic and Mammoth. Buses were ‘R’ names: Regal, Reliance and Regent. Engines were topped by 7.4-litre petrol and 7.7-litre diesel powerplants.

The engine was a AEC 7.58 1 6-cylinder, which developed an output of 95 hp. Top speed was 58 km/h light. The vehicle of course was a true 4x4, with independent suspensions on leaf springs, for off-road runs.

Engine: AEC 6-cylinder, type A173, 7.581 cm3 (462 cubic inches) displacement. Horsepower: 95 at 1.780 rpm. Transmission: 4-speed. Transfer case: 2 speed. Electrical system: Hybrid 12/24 volt. Brakes: Hydraulic, air-assisted, (early production), full air (late production). Tyres: 13.50 - 20. Fuel type: Diesel. Fuel capacity: 182 liter (40 gallons).

The shortage of petrol in WW2 saw the bus converted in 1943 for "producer gas" operation, whereby it towed a trailer which burned anthracite, producing gas to power the engine. It was one of very few LT single-deck vehicles to be selected for conversion.

Single-deck passenger chassis powered at first by the 6-type petrol engine, with subsequent options available during the 18 years Regal was in production comprising 7.4 litre 6-cyl petrol, 8.1 & 8.8 litre 6-cyl oil and the 7.7 litre 6-cyl oil.

Fitted with solid tyres it is powered by an AEC 4-cylinder 5.1 litre petrol engine of 35hp rating, and has a multiple clutch and 3-speed gearbox. In 1924 the S type appeared carrying single-deck bodywork the chassis being the same as that used for double-deckers.
