Perkins engine series

With a history stretching back more than 80 years, Perkins is one of the world’s leading providers of diesel and gas engines. Having always focused exclusively on the design and manufacture of engines, our range is aimed at the agricultural, construction, industrial, power generation and material handling sectors in the 4-2000 kW (5-2800 hp) range. Today, harvesters, excavators, forest machines, wheeled loaders and forklift trucks are just a few of the machines that are powered by a Perkins engine – all developed over the decades from those early tractor engines. The naming of our engines helps our customers to understand the capability of the engine, the letters and numbers defining the displacement and cylinders. From the 1000 series in 1999 and the need to confirm the emissions status letters were also added to number system.

Diesel engine cylinders

Multi-cylinder engines deliver smoothness and balance through their ability to neutralize imbalances by having corresponding mechanisms moving in opposite directions during engine operation. A multi-cylinder engine is capable of delivering higher revolutions per minute, as the piston stroke is reduced, decreasing the distance moved by the piston for each rotation of the crankshaft, which limits the piston speed for a given RPM. Typically more cylinders the higher RPM for a given displacement, although more cylinders mean higher frictional losses and complexity with which comes a potential additional cost. Smaller engines such as 2 and 3 cylinders are often simpler and more compact so that they can be used in smaller equipment, offer rugged reliability from fewer moving parts and provide reductions in fuel consumption. With more cylinders, 4, 6 and 8 cylinder engines provide improvements in use with reductions in noise, vibration, and harshness, to deliver a more comfortable operational experience and lower noise for use in urban environments

These are some of the Perkins heritage products that have been milestones along that journey.

P4/P6 series

The P4 and P6 engines, designed by Charles Chapman, the company’s original technical director, were launched at the 1937 Commercial Motor Show. They were compact and lightweight engines that established Perkins as a major supplier. The P6, producing 63 kW (85 hp) at 2600 rpm, and advertised as “The world’s lightest diesel engine” was an immediate sensation. The P4 and P6 were the platforms for many future award-winning engines.


The 6354, the straight-six, 5.7 litre successor to the P6, became the best-known diesel engine of its day and led to a rapid growth in sales for the company. Marine versions were popular for offshore racing. A P6354 painted in gold was exhibited in 1962 as our millionth export engine.


The first 4.236 came off the production line in August 1964 – the start of a 30 year domination of the agricultural and tractor market. It went on to power 4.5 million machines throughout the world.


The 8.36 litre V8.510 took Perkins products into a new performance range, producing 127 kW (170 hp) at 2800 rpm. It provided power in 1965 for a variety of trucks, coaches and heavy vehicles.

1000 Series

The 1000 Series of industrial and agricultural engines from 1999 was the Perkins response to a new era of emissions standards. The 4 and 6 cylinder engines covered a range from 67-134 kW (90-180 hp). A newly designed combustion chamber produced better emission control, lower noise levels and improved fuel consumption.

400 Series

Emissions standards were now a vital consideration in engine design. The new 400 Series introduced in 2001, designed to meet EU Stage II/U.S. EPA Tier 2, set new standards of quietness. It developed into a range of ultra-compact 2, 3 and 4 cylinder engines for a variety of applications in the agricultural, gardening, construction, electric power and materials handling sectors.

1100 Series

The 1100 Series had been launched earlier, alongside the 400 Series – and the

1200 Series

The tradition of innovation and excellence continued with the launch in 2013 of the 1200 Series, which was designed to meet the world’s most stringent emissions standards, Stage
