Answer 1

There are a few disadvantages but very few people know about these.

1) You spend double the amount on spark plugs when it is time to replace them.

2) The engine tends to overheat and loose power at higher speeds as compared to a single plug engine.

3) The engine wear and tear is somehow increased and hence these engines need frequent checkup and overhaul to keep the performance level constant.

4)  There may be a wierd kind of knocking sound on the machine.

5)  DTSi is actually a simpler, cheaper and low-tech alternative to making more power and burning less fuel.  However owners mistakenly think it is high-tech.
