Diesel engines are celebrated for their strength, durability, and ability to handle heavy loads. They power the global transportation and industrial sectors, from long-haul trucks and buses to construction equipment, ships, and trains. However, while diesel engines deliver impressive torque and performance, their efficiency is often limited by incomplete fuel combustion. Traditional diesel engines burn only about 70% of the fuel injected, leading to wasted energy, carbon buildup, and reduced performance over time.

Diesel-Hydrogen Assist Technology (D-HAT™) is redefining diesel engine efficiency by addressing these limitations. By introducing hydrogen into the combustion process, D-HAT™ improves fuel burn, leading to a dramatic increase in both engine torque and power output. This post explores how D-HAT™ works to boost diesel engine performance, making it a game-changer for fleet operators seeking more power and efficiency.

The Role of Torque in Diesel Engine Performance

To understand how D-HAT™ enhances diesel engines, it’s essential to first understand the importance of torque in engine performance. Torque is the rotational force that an engine generates to turn the wheels or drive the machinery it powers. In practical terms, higher torque means more pulling power, allowing diesel vehicles and equipment to:

• Haul heavier loads.
• Accelerate more quickly, even under heavy strain.
• Operate efficiently under demanding conditions such as steep inclines, rough terrain, or stop-and-go traffic.

For fleet operators, torque is a critical performance factor, especially in industries like transportation, construction, mining, and agriculture, where vehicles and equipment must move heavy loads efficiently. Diesel engines naturally produce more torque at lower RPMs compared to gasoline engines, making them ideal for these heavy-duty applications. However, improving torque and power while maintaining fuel efficiency is a constant challenge.

How Diesel Engines Lose Efficiency

Traditional diesel engines suffer from incomplete combustion, meaning that a significant portion of the fuel remains unburned after each combustion cycle. This unburned fuel turns into carbon deposits inside the engine, which reduce power output and cause long-term damage. The problem is further compounded by:

• Lower combustion efficiency: Diesel engines typically achieve only about 70% combustion efficiency, meaning 30% of the fuel energy is wasted.
• Slower combustion rates: Diesel fuel burns more slowly than other fuels, resulting in less energy being transferred into power during each combustion cycle.
• Increased emissions and buildup: The incomplete burn leads to the formation of particulate matter and carbon deposits, which clog engine components and reduce overall performance over time.

These factors limit the ability of diesel engines to produce maximum power and torque while remaining fuel-efficient. That’s where D-HAT™ comes in.

How D-HAT™ Increases Engine Torque and Power

D-HAT™ revolutionizes diesel engine performance by introducing a small amount of hydrogen into the combustion process. Hydrogen, as a fuel, burns far more quickly and efficiently than diesel, acting as a catalyst that enhances the combustion of diesel fuel. This faster, more complete burn leads to a significant increase in engine torque and power output.

Here’s how D-HAT™ boosts diesel engine performance:

1. Faster Combustion for More Power

One of the key benefits of D-HAT™ is that it accelerates the combustion process. Hydrogen burns around 10 times faster than diesel, which means that when it is mixed with diesel fuel in the combustion chamber, the entire fuel mixture ignites more quickly and completely.

• Earlier ignition: Hydrogen helps ignite the diesel fuel earlier in the power stroke, ensuring more of the fuel is burned before the exhaust valve opens. This maximizes the amount of energy released during each combustion cycle.
• More complete combustion: D-HAT™ increases the combustion efficiency of diesel engines from approximately 70% to as high as 93%, meaning less fuel is wasted, and more energy is used to power the engine.

With more energy being harnessed from the same amount of diesel fuel, the engine produces greater power output. This means the vehicle or machinery can do more work without requiring additional fuel, leading to improved overall performance.

2. Increased Torque for Heavy-Duty Applications

By increasing the combustion efficiency, D-HAT™ also enhances the torque generated by the engine. The faster burn of the hydrogen-diesel mixture provides more force during each power stroke, pushing the pistons down harder and delivering more rotational force to the crankshaft. This increase in torque translates into:

• More pulling power: Vehicles equipped with D-HAT™ can haul heavier loads more easily, reducing strain on the engine and improving performance in demanding conditions.
• Improved acceleration: Even under heavy loads, vehicles experience better acceleration, making them more responsive and efficient on the road.
• Better low-RPM performance: Diesel engines equipped with D-HAT™ can generate higher torque at lower engine speeds, which improves fuel economy and performance in applications where engines run at lower RPMs, such as in construction or agricultural equipment.

For fleet operators, these benefits are especially valuable in industries where maximizing load capacity and operational efficiency is crucial to profitability.

3. Improved Fuel Economy with More Power

One of the most significant advantages of D-HAT™ is that it increases torque and power without increasing fuel consumption. In fact, by improving combustion efficiency, D-HAT™ often reduces fuel consumption by up to 10%, delivering more power per gallon of diesel.

Here’s why:

• More energy from the same fuel: With hydrogen assisting the combustion process, more of the diesel fuel is burned completely, which means the engine generates more power with the same or even less fuel. This results in better fuel economy and reduced operational costs.
• Less energy wasted as heat: The more complete combustion process generates less heat and wasted energy, allowing more of the fuel’s energy to be converted into useful mechanical work.

For fleet operators, this means that vehicles and equipment can perform more work, haul heavier loads, and run more efficiently—all while consuming less fuel.

The Broader Impact on Engine Efficiency

In addition to increasing torque and power, D-HAT™ offers several other efficiency benefits for diesel engines:

1. Reduced Carbon Buildup

One of the major drawbacks of incomplete combustion in diesel engines is the formation of carbon deposits inside the engine’s cylinders, pistons, and exhaust systems. These carbon deposits reduce engine efficiency, increase maintenance needs, and shorten engine lifespan.

Because D-HAT™ promotes a more complete burn of the diesel fuel, it significantly reduces the formation of carbon deposits. This helps keep the engine cleaner, leading to:

• Longer engine life: Engines equipped with D-HAT™ experience less wear and tear, which extends their operational lifespan.
• Lower maintenance costs: Cleaner engines require less frequent maintenance, such as oil changes, filter replacements, and exhaust system cleanings.
• Improved long-term performance: Reduced carbon buildup ensures that the engine continues to operate efficiently, even after years of heavy use.

2. Cooler Engine Temperatures

Hydrogen burns faster and more completely than diesel, resulting in lower exhaust temperatures. This not only improves the combustion efficiency but also helps reduce the overall operating temperature of the engine.

• Less thermal stress on engine components: Cooler engine temperatures mean less wear and tear on critical components, such as the pistons, valves, and exhaust system.
• Reduced NOx emissions: Lower combustion temperatures also help reduce the formation of nitrogen oxides (NOx), which are harmful pollutants that contribute to air pollution and smog.

By keeping the engine cooler and cleaner, D-HAT™ not only improves performance but also contributes to environmental sustainability by reducing emissions.

Conclusion: A New Era for Diesel Efficiency

For industries that rely on diesel engines to power their vehicles and equipment, Diesel-Hydrogen Assist Technology (D-HAT™) represents a breakthrough in performance and efficiency.
