K B series engine

Developing a fuel efficient, high performance, low emission, light weight engine, with lower Noise, Vibration and Harshness

The new KB series engine is a result of enormous R&D efforts and hours of design, validation and testing.
The engine realises the true spirit of the global design trend of optimizing engine performance through innovative design techniques.

Some of the salient features of the All new KB engine are:

All Aluminum Low weight engine for Best in class fuel efficiency
Innovative rocker-less DOHC Cam shaft, Plastic Intake Manifold & Offset crank shaft with low tension rings to reduce losses & improve fuel efficiency
Smart Distributor Less Ignition (SDLI) system with dedicated plug top coils, High pressure semi-return fuel system and Advanced injectors for superior atomization provide uniform and optimized combustion for better performance
Optimised Cylinder block, Light Piston and Nut-less Con Rod for light weight configuration
Improved engine stiffness and use of advanced technology like silent timing chain to improve NVH (Noise, Vibration & Harshness) characteristics
These and many more innovative technologies used in the new light-weight KB series engines helped to achieve best in class fuel efficiency, emission & performance with reduced Noise, Vibration and Harshness for customer delight.The KB series engine will be mounted on the forthcoming model, A Star, from Maruti Suzuki.The KB-series engine, while fully complying with the prevalent BS III norms, is ready to meet the future emission norms in the country. The Engine meets the Euro V norms for the export model of A Star.

Chevrolet Volt

Its to be launched in 2011 which is not basicaly a hybrid model.It is being called as plug in series hybrid vehicle.Unlike current commercially available hybrids, the actual propulsion of the Volt is accomplished by the electric motor, as the ICE is not mechanically connected to the wheels. With fully charged batteries, this electric power will initially be sourced exclusively from its on-board Lithium Ion batteries for up to 40 miles (64 km),After 40 miles (64 km), the range of the Volt will need to be extended through the use of a small 4-cyl ICE which drives a 53 kW generator. The electrical power from the generator is then sent to either the electric motor or the batteries, depending on the state of charge (SOC) of the battery pack and the power demanded at the wheels. The distribution is controlled by the electronic control unit (ECU) of the vehicle.

It introduced the E-Flex drive system, which is an attempt to standardize many components of possible future electrically-propelled vehicles, and to allow multiple interchangeable electricity-generating systems. The initial design as envisioned in the Volt combines an electric motor and 16 kWh (58 MJ) lithium-ion battery plug-in system[33] with a small engine (1.4 liter) powered by gasoline linked to a 53 kW (71 hp) generator. The vehicle is propelled by an electric motor with a peak output of 120 kW (160 hp).
Since the electrical drivetrain is not affected by the method used to charge the batteries, several options could be available for acting as an electrical power source. The primary configuration specified in the Volt promotional literature uses a turbocharged 1.0-liter engine with three cylinders, a flex-fuel engine capable of running gasoline or E85 (85% ethanol, 15% gasoline).
E-Flex Powertrain


Another engine-driven power option would be a pure ethanol (E100) engine, a diesel engine capable of running biodiesel fuel, or even a hydrogen fuel cell, once that technology becomes practical.
