What Is Engine Torque?

Torque is the rotational force an engine generates, measured in Newton meters (Nm) or pound-feet (lb-ft). More torque typically means better towing power, pulling strength, and load-bearing capacity. In diesel engines like Perkins, high torque at low RPMs is particularly valuable in off-road and heavy-duty applications.

FAQs

How many horsepower is a 4 cylinder Perkins diesel?

The horsepower of a 4-cylinder Perkins diesel engine varies by model and series. For example, the Perkins 404D-22 produces around 48.7 HP, while the 1104D-44T delivers up to 100 HP. Modern 4-cylinder Perkins engines can range from 30 HP to over 130 HP, depending on turbocharging, emissions tier, and application.

What is the specs of the Perkins 6.247 diesel engine?

The Perkins 6.247 is a 6-cylinder, naturally aspirated diesel engine used in older tractors and industrial machines. It typically produces around 90–98 HP with a displacement of 6.1 liters (372 cu in). Peak torque is around 300–330 Nm at 1400–1500 RPM. It was widely used in agricultural and construction equipment in the 1970s and 1980s.

What is the correct torque for cylinder head bolts?

Cylinder head bolt torque for Perkins engines varies by model. For example:

• Perkins 400 Series: ~80–100 Nm
• 1100 Series: ~150–180 Nm
• 6-cylinder models: ~200–220 Nm
• Always refer to the official Perkins service manual for your specific engine model, as bolt stretch and sequence are also critical.

What is the spec of Perkins 1104C-44 engine?

The Perkins 1104C-44 is a naturally aspirated 4-cylinder diesel engine with:

• Displacement: 4.4 liters
• Power: 74.5 kW / 100 HP (approx.)
• Torque: Around 380–400 Nm @ 1400 RPM
• Applications: Used in agricultural tractors, loaders, generators, and industrial equipment
• It meets Tier 2 or Stage II emissions, depending on configuration.

How to calculate diesel engine horsepower?

To calculate diesel engine horsepower (HP), you can use the torque formula:

HP = (Torque × RPM) ÷ 5252 (for lb-ft)

or

HP = (Torque × RPM) ÷ 7127 (for Nm)

For example, if a diesel engine produces 500 Nm at 1500 RPM:

HP = (500 × 1500) ÷ 7127 ≈ 105 HP

How to identify a Perkins engine?

You can identify a Perkins engine by checking the engine serial number (ESN), typically found on a metal plate riveted to the engine block or stamped on the casting. The ESN includes:

• Engine family
• Build list
• Serial number
• You can use this number on Perkins’ official engine lookup tool or parts catalog to find full specifications, model, and parts compatibility.

Final Thoughts

Perkins engines have a long-standing reputation for durability, reliability, and efficiency. Knowing the torque output of your engine model helps you make smarter decisions about usage, maintenance, and upgrades. Whether you’re operating a compact generator or a large excavator, torque is the backbone of engine performance – and now, you have the figures at your fingertips.
