Tata Motors launches 'Revotron' - all-new family of next-generation petrol engines

Tata Motors announced the launch of the Revotron series, the next-generation petrol engine family that will power its future models in the passenger vehicle market. The company unveiled the first petrol engine from its Revotron series - the turbocharged intercooled
Multi-Point Fuel Injected (MPFi) Petrol Engine, Revotron 1.2T.

The Revotron series has been designed based on extensive feedback from car owners, car enthusiasts and expert drivers from across the globe; observing their driving habits followed by extensive testing in gruelling climatic conditions in India as well as in countries like the UK and Korea.

The Revotron series has been developed by Tata Motors with inputs from renowned global players in the area of combustion, boosting, friction and calibration, to deliver class-leading performance. Tata Motors also worked closely with global engine consultant AVL (Austria) and key technology partners like Bosch, Honeywell, Mahle and INA to bring in the latest technology for the new engine series. Revotron 1.2T has been tested for global standards along with a testing car by TEnergy of Korea to ensure that the engine performance is best-in-class.

The engine has been manufactured to belight on weight and low on friction, delivering high performance and fuel economy.The series will include 3-and 4-cylinder petrol engines to offer superior performance as well as high fuel efficiency to our customers.

"With the launch of Revotron 1.2T, Tata Motors passenger vehicles business is making a strategic shift towards a more complete portfolio. The name itself, an amalgamation of Revolution and the French word 'tronel', meaning 'balance', conveys the essence of this engine brand that uses key technological advances to revolutionise and balance great driving manoeuvrability, without compromising on power or fuel efficiency. We are enhancing our portfolio with the next-generation petrol engines - Revotron series," said Ranjit Yadav, President, Passenger Vehicle Business Unit.

The Revotron 1.2T has been engineered to deliver optimum balance of power, performance and fuel economy. Developed using a range of eco-friendly and future-oriented technologies,the next-generation petrol engine incorporates latest know-how like multi-drive modes,allowing the best of economy and driving pleasure. The Advance Engine Management Systems (AMS) provides a digitally precise control for vehicle performance and emissions and offers the design of reciprocatingcomponents to ensure the best out of every drop of fuel.

With enhanced customer benefits for the best driving experience, the Revotron series is therefore positioned to be a revolution in performance, refinement and economy, the three pillars of the Revotron series.

The engine is equipped with a HighBoost turbo-charger delivering 85 ps @ 5,000 rpm & 140 nm @ 1,750-3,500 rpm. The modern water-cooled turbo-charger, with its low inertia wheel, provides a faster response for a flat, seamless segment-highest torque density, which is kicked in at the lowest rpm and delivered over a wide range of revolutions, feeding the vehicle with raw power continuously. It's multi-drivemode, coupled with a superior throttle response, advanced catalytic converter with reduced Toxic Emissionsand Smart ECU (Electronic Control Unit) with various innovative strategies, ensure a superlative performance on Indian roads.

The engine is light-weight and powerful, with a stiffened crankcase that minimizes Noise, Vibration and Harshness (NVH) for a refined output. The engine is refined with tuned intake and exhaust system for improved combustion noise that is further reduced with silent-steel oil pan and lower auxiliary system noise. Enhanced with Smart (ECU) for precise control, the engine is powered by wire technology for a smooth and responsive drive experience.

The engine comes with another segment-first - a selectable multi-drive mode and uses low viscosity, fuel efficient engine oil. An optimised water-jacket and head gasket, using Computational Fluid Dynamics (CFD) technology, ensures efficient combustion and reduces thermal inertia. In addition, the engine has been incorporated with an 8-hole fuel injector for superior efficiency and assisted by innovative calibration strategies.
