Dual VVT

The DualJet engine also utilizes Dual Variable Valve Timing (Dual VVT), which allows precise control over the opening and closing of the intake and exhaust valves. By adjusting the valve timing according to the engine’s operating conditions, the Dual VVT system maximizes power output while minimizing fuel consumption.

Lightweight Design

Maruti has prioritized lightweight design in the development of the 1.0 DualJet engine. By utilizing lightweight materials and innovative engineering techniques, the engine’s overall weight is reduced, resulting in improved fuel efficiency. The lighter engine requires less energy to propel the vehicle, translating into better mileage.

Efficient Combustion

Efficient combustion plays a vital role in achieving fuel efficiency. The DualJet engine incorporates various technologies that promote efficient combustion and maximize fuel utilization.


To enhance combustion efficiency, the DualJet engine creates controlled turbulence within the combustion chamber. This turbulence promotes better air-fuel mixing, ensuring a more complete and efficient combustion process.

High Compression Ratio

The engine’s high compression ratio is another factor contributing to its fuel efficiency. A higher compression ratio allows for more efficient combustion of the air-fuel mixture, extracting maximum energy from the fuel.

Improved Cooling

Efficient cooling is essential for optimal engine performance. The DualJet engine incorporates an improved cooling system that maintains the engine at an optimal temperature range. By preventing overheating, the engine operates more efficiently and minimizes fuel consumption.

Advanced Control

Advanced engine control systems are employed in the DualJet engine to precisely monitor and adjust various parameters in real-time. This intelligent control enables optimal fuel delivery, ignition timing, and other critical engine functions, further enhancing fuel efficiency.

Smooth Performance

While prioritizing fuel efficiency, Maruti has also ensured that the 1.0 DualJet engine delivers smooth and enjoyable performance.

Balanced Power Output

The DualJet engine strikes a balance between power and fuel efficiency. It delivers ample power for a comfortable driving experience while optimizing fuel consumption. This balance ensures that drivers can enjoy a spirited drive without compromising on efficiency.

Low Friction

Reducing friction within the engine is crucial for fuel efficiency. Maruti has incorporated various friction-reducing technologies in the DualJet engine, such as low-friction piston rings and optimized bearing designs. These measures minimize energy losses due to friction, resulting in improved fuel economy.

Eco Assist Technology

To assist drivers in achieving optimal fuel efficiency, Maruti has equipped the DualJet engine with Eco Assist technology. This technology provides real-time feedback on driving behavior and suggests adjustments to maximize fuel economy. By promoting fuel-efficient driving habits, the Eco Assist technology contributes to better mileage.

Enhanced Fuel Economy

The combined effect of all these innovative features results in enhanced fuel economy, offering significant benefits to the drivers and the environment.

Real-World Benefits

In real-world scenarios, the Maruti 1.0 DualJet engine showcases remarkable fuel efficiency. Drivers can enjoy longer trips with fewer refueling stops, saving both time and money. Additionally, the reduced carbon emissions contribute to a greener environment, making the DualJet engine a sustainable choice.


Maruti’s new 1.0 DualJet engine is a testament to their commitment to developing fuel-efficient and performance-driven vehicles.
