What does twin spark engine mean?
Variable valve timing gave the Twin Spark engine very good performance for its cubic capacity, but it is one of the weaker areas of the 16-valve engine
. The original variator that controls the cam timing is prone to wear or jam, although replacement part carries a different part number and has improved reliability.
How do twin spark engines work?
The logic behind this technology is that
two spark plugs can burn the fuel/air mixture much quicker than a single spark plug by ignition at two different points at once
thereby giving twin spark engine cars a greater efficiency.
Why do some engines have 2 spark plugs per cylinder?
By having two spark plugs per cylinder,
your aircraft engine is more reliable, produces more power, and burns fuel more evenly
. And when you combine all three, you get an ultra-reliable engine that keeps you aloft until you decide it's time to land.
What is meant by DTS i engine?
DTS-I stands for
Digital Twin spark ignition
. Basically, it has two spark plugs at the opposite end of engine cylinder head in 90 degrees; instead of one spark plug which is common in a conventional engine. Two spark plugs produces the spark during the power stroke according to input requirement.
How does Dtsi engine work?
DTSI is Digital Twin Spark Ignition. In normal engines, there will be only one spark plug generating sparks at a regular interval.
DTSI has twin spark plugs which create sparks alternately
. This means that in a given time frame there will be double the nunber of sparks than in the normal engine.
Iridium spark plugs feature
a fine wire center electrode that is designed to conduct electrical energy better and increase firing efficiency
. There is a price for this precious metal. Iridium spark plugs are typically the most expensive, ranging from $8 to $15 each.
The new 1250 BMW
twin-cylinder
boxer engine stands out for its versatility and, thanks to the BMW ShiftCam, is impressive in every riding situation and on every terrain. Each model of the new R 1250 series benefits from control, refinement, acceleration, sovereignty and higher performance from the new engine.
A
spark-ignition engine
(SI engine) is an internal combustion engine, generally a petrol engine, where the combustion process of the air-fuel mixture is ignited by a spark from a spark plug.
Advantages of DTS-i :
Increase power output
. Better low-end torque. Optimization of spark timing. Low emission level.
Multiple ground electrode designed spark plugs
significantly slow down the early flame development
, due to the increase in heat loses and the reduction in flame growth due the restricted flow directions.
With a V12 engine, there are
12
spark plugs. You want to look at each one to see if it is wearing properly.

NGK stands for
Nihon Gaishi kabushikigaisha
, the Japanese name of NGK Insulators.
Modern engines demand more power while using less fuel, shortening the life of traditional iridium and platinum spark plugs.
NGK's patented ruthenium technology stands up better to wear to bring maximum durability and performance to your engine
.
Three
spark plugs are employed to provide best in class performance and efficiency.
In a wasted spark system,
the spark plugs fire in pairs, with one plug in a cylinder on its compression stroke and the other plug in a cylinder on its exhaust stroke
. The extra spark during the exhaust stroke has no effect and is thus “wasted”.
The Boxer engine is better balanced, has a lower center of gravity, and occupies shorter space than an inline
. However, it's more complicated, expensive, and harder to maintain, leading to reliability issues.
Modern boxers are easily
200,000 miles
bikes if maintained and ridden responsibly. Also, BMW does a reasonably good job of maintaining parts for older models so, if your BMW needs a part, it is likely available.
Thermal efficiency: Due to lower compression ratio,
maximum value of thermal efficiency is lower in an S.I engine compared to that of C.I. 7
… Weight : S.I engines are generally lighter in weight due to their lower peak pressures as compare to C.I engines that are generally heavier, due to higher peak pressure.
