Why The Pulsar 200 NS Has 3 Spark Plugs

Posted: 28 Jul 2012 04:47 AM PDT


The Bajaj Pulsar 200 NS is now in its second generation. The Pulsar has taken a massive leap in terms of engine refinement, handling, braking and performance. However some people are not too sure about the technology used in the motorcycle. We have often got questions about why the Pulsar 200 NS has triple spark plugs? Many people even ask that when the KTM Duke 200 has one spark plug and the Kawasaki Ninja 650R has two spark plugs (being a twin-cylinder bike), why does Bajaj Auto use three spark plugs in the Pulsar 200 NS? The question does hold weight-age as prospective buyers would want to know about the technology used in their bike. We got in touch with Bajaj Auto and they told us why they used triple spark plugs in the new Pulsar.

As can be seen in the above picture, the Pulsar 200 NS’ engine has two slave plugs (similar in spec) on either side and one master plug on the top. Twin spark plugs on either side are in-adequate to achieve the combustion efficiency which Bajaj engineers were looking for in the 200 NS. Thus the need for a center spark plug was felt by the engineers. Bajaj says that if the Pulsar 200 NS had only twin spark plugs, the combustion efficiency would be better than single spark plug by 18%. However with triple spark plug the efficiency is better by 27% than the twin spark plugs.

Bajaj Auto has used a ‘over-square’ configuration in the Pulsar 200 NS (bore x stroke of 72 x 49). The old Pulsar 200 had a bore x stroke of 67 x 56.4 which was a square configuration. The reason to opt for a ‘over-square’ configuration is for better top end performance, which is facilitated by the 4-valves, the company claims. So overall, the triple spark plugs are touted to improve combustion, thereby boosting performance and at the same time maintaining a good fuel economy for the Pulsar 200 NS.

Meanwhile feast your eyes on some interesting pictures from the development of the Pulsar 200 NS.

2013 BMW X6 Facelift

BMW India has just launched the new 3-Series (F30) and has planned four more launches for 2012. We already know that BMW will be bringing in the facelifts of the X1 and 7-Series later this year. At the launch of the new BMW 3-Series, the company also confirmed its plans to bring in the new 6-Series Coupe and facelifted X6 within the next five months. Both these cars will be brought in via the CBU route. These upcoming launches clearly show how aggressive BMW is about the Indian market, which will help them maintain a clear lead ahead of its German rivals, Audi and Mercedes-Benz.

The 2013 BMW X6 gets minor styling tweaks, such as new head lights, slightly changed front grille, new front bumper, new alloy wheels and new tail lights. The interiors have got minor tweaks as well and the 4-seater X6 is offered in new colors, including Marrakesh Brown metallic. The engine options on the new BMW X6 remain the same though and the Bavarian automaker will offer the SAV in xDrive30d and xDrive50i variants. These engines produce 245 BHP and 400 BHP respectively. Currently the BMW X6 (30d) is priced at Rs. 1.05 crore, while the BMW X6 (50i) is priced at RS. 1.24 crore (on-road, Mumbai).

BMW India will also launch the 2013 6-Series Coupe, whose chassis has been tweaked to give it better handling characteristics. The company has also added the M-specific power steering along with a more powerful braking system. The new BMW 6-Series Coupe will be offered in two variants, 640d and 650i. The BMW 640d is powered by a 3.0-litre turbocharged engine which produces 308 BHP of peak power at 4400 RPM and a massive 630 Nm of peak torque between 1500 and 2500 RPM. This helps the 640d in reaching 100 km/h in just 5.2 seconds and yes that is a diesel engine underneath the hood.

The BMW 650i is powered by a a 4.4-litre V8 petrol engine which produces 400 BHP of peak power between 5500 and 6400 RPM and 600 Nm of peak torque between 1750 and 4500 RPM. The 650i reaches 100 km/h in 4.5 seconds. If you still want more performance, there is an optional M package on offer too. Both the 640d and 650i are mated to a 8-speed automatic gearbox and have a top speed limited to 250 km/h. Currently the BMW 640d Coupe is priced at Rs. 1.09 crore, while the BMW 650i Coupe is priced at Rs. 1.186 crore (on-road, Mumbai).
