India’s first ever BS-IV compliant engine with best in class fuel efficiency.

Gurgaon : Maruti Suzuki unveiled the new K12M for its soon to be launched hatch back Ritz. The K12M is BS-IV compliant engine. This is the first time that a BS-IV engine will power any passenger car in the country. This new 117cc Aluminum engine is the second in the K series and retains the technological superiority and fuel efficiency of the K10B engine which powers the Maruti Suzuki A-Star. 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-Stars K10B engine.

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 the 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 of CO2 emissions.  The K12M engine further strengthens Maruti Suzuki’s effort for fuel efficient, green engine technology for customers in India"

K12M engine reflects the company’s continuous 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 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 advance 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 developing the engine development capability. The engine promises to be best in class fuel efficient, high performance, low emission, light weight with lower NVH (Noise, Vibration and 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; where as 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 Crankshaft with low tension Rings to reduce losses and increase fuel efficiency.
* Smart Distributor Less Ignition (SDLI) 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 change over time from 1000KM 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.
