Mazda SkyActiv 1.5 Engine Troubleshooting and Repair
Mazda SkyActiv 1.5 engine is a fresh motor from the SkyActiv series, which replaced the MZR motors, and the 1.5 liter displaces the outdated 1.6 Z6. SkyActiv 1.5 liter comes in two types, with a compression ratio of 13 and 100 hp and with a compression ratio of 14, with 120 hp.
All motors use direct fuel injection, the system of changing the phase of gas distribution on the intake and exhaust shafts Dual S-VT, light connecting rod and piston group, the pistons themselves a special shape for maximum optimization of the combustion process and reduce the likelihood of detonation, at the same time, already from the factory installed spider 4-2-1 such a length that there was an effect of blowing the cylinders, all this allows the motor SkyActiv to work at a compression ratio of 14 without the occurrence of detonation and show 120 hp from a small working volume.
Despite this, Mazda 3 with SkyActiv 1.5 does not go very well, the power is still not enough and if you have the means, you need to take 2.0 liter.
One and a half liter motors Skyaktiv, fresh enough and information on their problems and shortcomings is very little, the article will be completed as the data arrives.
Motor tuning
Chip tuning SkyActiv 1.5
SkyActiv tuning is a simple matter, go and flash, about 5% hp will be added, whether you feel it or not is another question. It will not work out thoroughly, there are no tuning camshafts on the market, the spider is already there from the factory, to put a compressor or turbine on a motor with such a prohibitive compression ratio means the motor will fall apart instantly, to change the piston and reduce the compression ratio means that the meaning of the idea of Skyactiv is lost.
Bottom line, you want to add up to 5% chip Mazda 3 SkyActiv engine, you want more, take other motors.
