Trucks on methane: how many saves? (spoiler — really!)

A year after the conclusion to our market a new line of Scania machinery appeared modifications of the methane series P, G and R with an infinite number of variations of cabin, wheel formula and capacity.Alexander Vinogradov “Behind the wheel”

Fuel costs eat up the lion’s share of the budget carriers. Even with a very competent logistics and fresh Park the cost of fuel — at least one-third of income, and sometimes reach half! Outputs two. First: to reduce fuel consumption — but here the limit is already almost reached. Second: use cheap fuel. And what could be more affordable natural gas?

Gas engines for a new range of Scania trucks a choice of two five-cylinder (9.0 l, 340 HP) for Junior cabin series P and G and 13‑liter row “six” for series G and R (up to 410 HP). The motors are almost equal in torque similar to the power diesel engines and trucks is extremely important.

Methane engines as conventional diesel, operate on the Otto cycle with all the consequences — spark ignition and low compression ratio. Standards of toxicity Euro‑6. And no urea is not necessary. All the trucks on CNG is equipped with robotized transmission Opticruise.

Row 13‑liter “six” OC13 produces 410 HP and 2000 nm at 1100-1400 rpm Inline 13‑litre “six” OC13 produces 410 HP and 2000 nm at 1100-1400 R/min.

The engine is lighter than diesel, but the overall vehicle weight increased by a half — ton cylinders for a solid reserve a lot.

It would be possible to put a lightweight composite instead of steel, but there are other difficulties. Verification of these cylinders is mandatory every six months, and the service life is 10 years. The steel life cycle twice, and the verification is carried out every five years.

The total volume of the cylinders is 190 m3. This reserve lasts an average of 500 km.The total volume of the cylinders is 190 m3. This reserve lasts an average of 500 km.

Main silence

In front of me — the main tractors 4×2 and 6×4, dump truck, loader, hooklift.

First, climb into the tractor R410 13‑liter engine. Let the engine and affected silence: no vibration, no background noise, so characteristic of diesel engines. A gas engine is incredibly quiet and the traffic situation does not change — only light roaring winds in the mirrors Yes the rustling of tires.

In addition to gas engines, Scania showed another novelty for Russia — G410 truck with the wheel formula 8×4/4 with a rear “truck” on three axes.In addition to gas engines, Scania showed another novelty for Russia — G410 truck with the wheel formula 8×4/4 with a rear “truck” on three axes.

Pull a good tractor calmly pulls six percent in the rise of a great trailer. The motor really carries no worse than a diesel.

9-liter “five” OC9 swagger already can not wait, and it is not necessary. It is put on the technique easier. I chose the most colorful — bright blue garbage truck P340. It is almost the only Scania, which doesn’t have a retarder. Because the slopes of the Dmitrov autorange had gently work the brakes, so as not to burn them to hell. However, habitat “musorovoz” habitat is the city where the retarder is unlikely to be useful.

To control the retarder is simple. The intensity of deceleration is adjustable from the steering column stalk, speed on descent — switch on the hub of the steering wheel.To control the retarder is simple.

A compressed budget

Was it worth the gas to fence the garden? Savings per kilometer due to cheap fuel is from 6 to 9 rubles. With an annual mileage of 200 000 km, Scania gas will help keep half a million rubles. But if in the Park ten cars?

Another trump card: the estimated resource is gas-engine overhaul — 2 000 000 km. Because there is no shock “diesel” loads of sulphur in the fuel and, as a result, deposits and coking.

What’s the catch? In reserve. Gas in the total volume of 190 m3 cylinders lasts an average of 500 km For long-haul tractor — bit. And methane gas stations in our great gas power is still very tight.

However, the Park-methane Scania is growing: the company doing this for multi-million dollar savings on fuel. Gazs even build in their own territory: if the Park ten or more cars, it’s a good idea — can be recouped in the third year. And there, staring, and the number of methane filling stations in the country will increase.
