Maruti Suzuki, India's number one car-maker, unveiled the all-new K12M
engine for its soon-to-be-launched hatchback Ritz. The K12M is BS-IV
compliant engine. This is the first time that a BS-IV compliant engine
will power any Passenger car in the country. This new 1197cc all
aluminum engine is the second in the Kseries and retains the
technological superiority and fuel efficiency of the K10B engine which
powers Maruti Suzuki A-star.
Unveiling the new engine Mr. Shinzo Nakanishi, Managing Director & CEO,
Maruti Suzuki, said, "K12M engine is another example of Maruti Suzuki's
commitment to take engine technology in India to the next level. This is
in line with parent company, Suzuki Motor Corporation's focus on
maximizing the environmental benefits of fully proven technologies. For
this, Suzuki is fully exploiting the know-how gained in over 50 years of
compact-car production. K-series engine is the latest innovation coming
from this focus. K series engines are not just fuel efficient but also
low on CO2 emissions. The K12M engine further strengthens Maruti
Suzuki¿s efforts for fuel efficient, green engine technology for
customers in India."
The K12M engine is being manufactured in Maruti Suzuki's brand new
state-of the-art engine manufacturing facility inside its Gurgaon plant,
which was inaugurated last year with the launch of A-star's K10B engine.
The K12M engine reflects the company's continued focus on investment in
long term strategic projects which include expansion of manufacturing
capacity and introduction of new engine technology.
The first car to be fitted with this brand new K12M engine will be the
forthcoming premium compact car Maruti Suzuki Ritz. The Ritz will be yet
another compact car to join the company's A2 (compact car) offering that
include Alto, Zen Estilo, A star, Wagon R and Swift Petrol and Diesel.
The Ritz is in advanced stage of preparation for a formal launch
shortly. With a new technology engine, the Ritz will be positioned in
the upper end of the growing compact car segment.
The K12M engine has been specifically designed for Indian applications.
Maruti Suzuki's engineers worked as part of Suzuki's Engine Design team
for the design, calibration and testing of the engine in Japan and in
India. This is a step forward in enhancing the engine development
capability. The engine promises to be a best in class fuel efficient,
high performance, low emission, light weight, with lower NVH (Noise,
Vibration & Harshness).
Like the K10B engine, plastic parts have been extensively used in K12M
engine as well. The skirt area of the piston has been shortened to make
the aluminum engine lighter, whereas the resin-coated piston helps
reduce friction and increase fuel efficiency.
Some of the salient features of the all new K12M are:
|
- All Aluminum low-weight engine with best-in-class fuel
efficiency
- Innovative Rocker-less DOHC cam shaft, Plastic Intake Manifold
and Offset Crank shaft with low tension Rings to reduce losses and
improve fuel efficiency.
- Smart Distributor Less Ignition (SDLI) system with dedicated
plug top coils, High pressure Fuel system and Advanced Injectors for
superior atomization to provide uniform and optimized combustion for
better performance
- Optimized 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 characteristics

Lower running costs:
|
- Higher Grade Engine Oil: Improves first changeover time from
1,000 Km to 10,000 Km
- Increased Spark Plug Life: Spark Plug change over time has been
changed from current 20,000 Km to 40,000 Km
- Silent Timing Chain: Longer life in comparison to conventional
Belt Design
- Valve Clearance Adjustment: Due to Tappet Design, Valve
clearance re-adjustment frequency has been reduced.
