we Already know that Mazda is nothing unconventional to the design of engines with the technology SKYACTIV, and today we tried another of those initiatives that have been undertaken Mazda to make a simple diesel engine of 1.5 liters is just as valid to love with the diesel as it is for fans of the gasoline. After joining the Mazda 2 and Mazda CX-3, we tested the new engine 1.5 SKYACTIV-D 105 HP in the Mazda 3. We have tested, analyzed and put up against the strings and these have been our findings.

Browse the unconventional has its advantages, but without a doubt it is a philosophy very risky. Thus, in the present Mazda is the living embodiment of doing things differently to deliver the same result, a philosophy or technique that applies to their products, and especially their engines. While the entire automotive industry bet by the downsizing on the petrol engines, they invest more to improve the atmosphere. In the same way, if the trend in diesel is to reduce its emissions to base of engines increasingly complex and technological, Mazda have taken a very interesting way that speaks of low compression ratios, a lot of optimization and the compliance, anti-pollution more demanding without requiring any type of system, NOx-Trap or SCR with AdBlue to neutralize the so fashionable emissions NOx.

How has designed Mazda your engine 1.5 SKYACTIV D?

The engine 1.5 SKYACTIV-D meets the Euro 6 without the need for complex and expensive systems, anti-pollution

But let us focus on the 1.5 SKYACTIV-D. This engine is one of the great expected in the range Mazda 3, since by his power of 105 HP and a consumption approved of 3.8 l/100 Km (NEDC), it is a safe option when buying a car for its price/performance ratio consumption/performance. This new engine is intended to be done with 25% of sales in the Mazda 3, while the other 25% distributed in the engine 2.2 SKYACTIV-D 150 HP, and the remaining 50% in the version gasoline 1.5 and 2.0 SKYACTIV-G. Although Mazda strengthens exceeding its supply diesel with the arrival of this new engine, the trend of the market continues to reveal a greater predilection for the petrol engines.

level design, engine 1.5 SKYACTIV-D 105hp stands out by offering a very low compression ratio, 14,8 to 1 (the lower market), a system of EGR dual-stage, the use of a variable geometry turbocharger with speed sensor of the gas admission and a system, anti-pollution, which dispenses with any element destined to remove the NOx. The goal of Mazda with all these elements is to lower the combustion temperature as much as possible, thereby reducing the losses due to heat, and in the same way, thus avoiding the formation of NOx.

Your running away from what we are used to a diesel, and that is an added value

But the improvements of this design do not end here, and that is the engine 1.5 SKYACTIV-D 105hp is also notable for offering a margin-of-use fairly large for what is expected of a diesel with a scheme of work that stretches up to the 5,700 rpm and a special care to limit vibration and harshness of an engine turbo. The comfort of use is a point where Mazda has become a special interest, and for this he has designed the system “Natural Sound Smoother”, which consists of a plunger that is specific to the pistons that get damp vibrations up to 3.5 kHz. Without being able to know for certain how effective the system is, what is true is that smoothness and absence of vibrations is quite remarkable, thus allowing to get rid of all those disadvantages that offers a diesel engine common when you want to convince a regular to petrol engines.

Not everything would be advantages, and is perhaps the escalation of this diesel engine is what many users accustomed to diesel engines, you will not understand. Let Me explain. Bridging the gap, this diesel engine is the closest thing I have driven to a petrol engine maximum power. It does not offer a torque delivery explosive, your figure of fact is 270 Nm, which makes it a motor elastic and that it meets, but at no time does displays of excessive character. Those who need increased strength in the answers must opt for the block of 2.2 liters and 150 HP, an important step, but that will only be necessary for those who truly seek a much faster engine and energetic. There is a block of 120 HP based on the 1.5 SKYACTIV-D, it would be easy to convince the 90% of the customers looking for a Mazda 3 diesel.

The Mazda 3 1.5 SKYACTIV-D 105hp-up

After knowing what offers this engine, and what we cannot expect from it, it is a good time to uproot and head to the path that he has prepared for Mazda to analyze how it’s going this mechanic fueled by diesel. We speak of a journey of over 100 kilometres, alternating all kinds of scenarios and which has not been sought to offer the best consumption, rather the opposite to make numerous stops and changes of direction.

For those used to a diesel engine, the first thing you do notice is the low noise and virtually zero occurrence of vibrations. It is a quiet motor, it does not note cold, and even less in hot. This test was done at the wheel of a Mazda 3 SportSedán with manual change of 6 relations. Developments of change are long, but the selector has a few routes correct and the elasticity of the engine allows you to not have to pull the change to retrieve revolutions if you are traveling to very low turns. The Mazda 3 is shown as a car that is agile, at least when you move to two occupants and a luggage of two suitcases in hand. The 105 HP of this engine to meet the bulk of the situations, being seen only insufficient in the case of move more passengers or more luggage.

Prices of the Mazda 3 with engine 1.5 SKYACTIV-D 105hp

The new engine 1.5 SKYACTIV-D 105hp is available in the body Mazda 3 5 door and Mazda 3 SportSedán.
