Learning About How Different Types of Fuel Might Affect Your Engine Choice

(And How to Choose the Best One for Whatever You’re Going to Use It For)

Understanding how different fuel types can affect your choice in engines

When buying a new engine—commercial, industrial, or heavy-duty use—choosing the right type of fuel is more than just a choice. Performance, efficiency, operating expense, and long-term dependability can be heavily affected by it.

In this in-depth guide, we will make you aware of how different fuels—diesel, petrol (gasoline), natural gas, propane, and alternative fuels—affect your engine choice. We will present real-world application, contrast engine specs, and show you why our engines may be the smartest investment for you.

Why Fuel Type Matters When Choosing an Engine

Before we delve into specifics, here’s why fuel type is at the top of your list of things to consider:

• Performance & torque output
• Fuel efficiency & operating cost
• Environmental considerations (emissions)
• Availability and support infrastructure
• Initial cost vs. long-term benefit
• Maintenance & service requirements

Each engine we stock is designed to meet a specific use case, environment, and operating requirement. Let’s take apart how each type of fuel affects engine choice.

1. Diesel Engines: Power & Endurance

Best For: Industrial use, construction equipment, heavy-duty vehicles, generators

Key Specifications of Our Diesel Engines:

• Power rating: 50 – 1500 HP
• Torque: High low-RPM torque
• Fuel economy: 0.30–0.45 lb/hp·hr
• Emissions: Tier 3 to Tier 4 Final compliant
• Longevity: Up to 30,000 hours of maintenance

Pros:

• Good fuel efficiency
• Long engine life
• Heavy-duty torque
• Reliable starts under load and in deteriorated conditions

Cons:

• More up-front cost
• More emissions than alternatives (but declining with DEF systems)

Example Use Case:

If you have a fleet of construction vehicles or industrial generator set, a diesel engine provides the power and endurance you need. It is quiet during load operation and easy to service in off-road areas.

2. Petrol (Gasoline) Engines: Light and Economic

Best For: Light cars, light equipment, backup power generators

Features of Our Petrol Engines:

• Power rating: 20 – 500 HP
• Torque: Moderate at higher RPMs
• Fuel consumption: 0.45–0.55 lb/hp·hr
• Emissions: Models available that meet EPA standards
• Lifespan: 10,000–15,000 hours on average

Advantages:

• Lower initial cost of purchase
• Quieter and smaller, smoother operation
• Smaller design

Disadvantages:

• Lower fuel-efficient consumption compared to diesel
• Not ideal for heavy continuous load use

Use Case Example:

Ideal for mobile utility vehicles, light construction equipment, and short-cycle generators. Petrol engines are low maintenance, start up quickly, and low initial cost.

3. Natural Gas Engines: Clean Energy for Fixed Applications

Best For: Fixed sites, commercial structures, power generation

Main Specifications of Our Natural Gas Engines:

• Power output: 100 – 1200 HP
• Fuel economy: Similar to diesel but gas quality dependent
• Emissions: Ultra-low NOx versions available
• Life expectancy: Up to 20,000 hours with proper maintenance

Benefits:

• Reduced emissions
• Low-cost and abundant fuel source
• Smooth and quiet operation
• Government incentives in some locations

Restrictions:

• Requires a piping or storage system
• Not ideal for mobile or remote application

Use Case Example:

Running a commercial factory or large facility? A natural gas engine is an affordable answer to stationary power of extended duration, with the bonus of reduced emissions.

➡️ Require a clean source of energy? Examine our natural gas engine product family.

4. Propane Engines: Clean Burning & Versatility

Best For: Forklifts, fleet trucks, backup generators

Key Features of Our Propane Engines:

• Power output: 30 – 400 HP
• Fuel consumption: Slightly higher than diesel
• Emissions: Lower CO2 and particulates
• Lifetime: Comparable to petrol engines

Benefits:

• Clean-burning fuel
• Easy refuelling through tanks
• Lower engine deposits lead to longer servicing times

Drawbacks:

• Fuel might not be as readily available as diesel/petrol
• Higher cost of operation should the fuel infrastructure hasn’t been put up

Example Use Case:

For backup generators, logistics fleets, or stockroom trucks, propane engines offer a high-performance, low-emission solution in tight spaces.

➡️ Consult with our sales staff your number one propane engine for your fleet.

5. Alternative Fuels: Future Is Now

Options Are: Hydrogen, biodiesel, ethanol blends, electric hybrids

Why Use Alternative Fuel Engines?

• Lower carbon footprint
• Incentives from the government or green certification
• Greater congruence with ESG (Environmental, Social, Governance) goals

We continue to increase our product line engines with renewable fuels. They are designed to perform and sustain.

Example Use Case:

The largest beneficiaries of engines which will take biodiesel or blended fuel are municipal fleets, farm machinery, and green buildings.

➡️ Contact us for models now available which are dual-fuel or biofuel capable.
