Subaru legacy двигатель схема

Мотор ej204 берет свое начало от оппозитного двигателя ej20. Проектировались оба двигателя на заводе Gunma Oizumi Plant. Данная компания принадлежит Subaru. Разработка силового агрегата производилась преимущественного для внутренних потребностей.

Главным отличием двигателя ej204 от конкурентов является его оппозитная конструкция. Мотор имеет четыре цилиндра. Каждый поршень с шатуном размещается на отдельной шейке коленвала. Головка блока цилиндров совсем не похожа на гбц, устанавливаемую на рядные двс. Горизонтально-оппозитные моторы стали фирменной особенностью автомобилей Субару.

Руководство компании уделят много внимания внедрению новшеств, поэтому модернизация двс происходит достаточно часто. Из-за этого мотор ej204 имеет массу моделей, зависящих от поколения автомобиля, рынка сбыта, года изготовления и прочих факторов. Технические характеристики разнятся достаточно сильно. Так степень сжатия ej204 может быть от 10.0 до 11. Единственное, что остается стабильным — порядок работы цилиндров. Изменения, вносимые изготовителем, затрагивают:

  • выпускной коллектор, который может иметь различные системы рециркуляции разгоряченных газов;
  • зажигание, имеющие ушедшие от унификации катушки;
  • распредвал;
  • коленвал;
  • топливную рампу, в результате чего система питания мотора претерпевает множество сопутствующих изменений;
  • навесное оборудование, преследуя цель в виде упрощения демонтажа и монтажа двс на автомобиль;
  • маховик;

Оппозитное расположение поршней позволяет успешно гасить возникающие посторонние вибрации. Звук работы мотора намного тише и имеет специфичный субаровский оттенок. Использование данного двигателя позволяет снизить центр тяжести, что существенно улучшает динамические показатели автомобиля.

Не лишен мотор и недостатков. Нестандартная конструкция усложняет его техническое обслуживание и это при том, что характеристики двигателя не превосходят рядные варианты двс того же объема. Так, например, заменить свечи на ej204 достаточно проблематично из-за сложности доступа к ним. Следует учитывать, что силовая установка более чувствительна к тому, какое масло используется. Да и капитальный ремонт провести могут не на всех СТО, поэтому многие автовладельцы решаются на приобретение нового мотора. Также недостатком всего семейства ej20 является ситуация, когда обрыв ремня ГРМ гнет клапана.

What is wrong with the 2020 Subaru Outback and Legacy?

One of the greatest upgrades rolled out for both the 2020 Subaru Outback and Legacy was an available 11.6-inch vertically oriented infotainment screen. However, this very screen is that the core of this newest issue. Additionally, the base infotainment screen is also affected. According to CarComplaints, this newest issue surrounds the rear back up camera specifically. In short, the camera display randomly goes blank during operation.

According to CarComplaints, this unusual issue currently affects 6,768 Subaru Outback models and 973 Legacy sedans. To resolve the issue, Subaru decided to roll out an over-the-air update. The update reached customers between August 17th and 21st of this year. Unfortunately, the software update could not fix the issue, pointing toward a potential hardware issue that needs addressing.

Perhaps even more significant, however, is what Hurtig describes as a need to “rebuild the dealer network from the roots”.

He explained: “We’ve changed a lot of things within Subaru UK. We also need to change the structure of our dealer network entirely. There’s a lot of things we lacked in the past – from both sides of the business. I’m not just blaming the dealers; 50% [of the blame] goes back to us as an organisation as well.”

While he acknowledges that there’s a “core” need for more Subaru presence in the UK, both in terms of dealers and investing more in marketing and brand awareness activities, more pertinent is actually getting those dealers engaged in the brand and on-message.

“We need the right dealers,” he said. “It comes back to that. We can have the best marketing and brand awareness, but if the dealers aren’t on the same page, it’s useless. So this has to be developed hand-in-hand.”

Hurtig has an “aggressive” plan to expand the network in the UK, hoping to establish 15 new sites this year alone, as well as bringing a “new attitude” across the board.

Subaru also still finds itself suffering from a confused brand image that it must overcome. In the 1990s and 2000s, its reputation was firmly bolstered by the rallying success of the Impreza WRX STi, a model with a huge legacy that gradually fell out of favour in the face of a European hot hatchback boom and was killed off in the UK entirely in 2018.

“Subaru UK has made a lot of mistakes in the past, to build Subaru’s brand to be something it isn’t any more,” said Hurtig. “[The Impreza] was a performance car, a rally car. It was a good era in UK. But it’s history; it’s a long time ago now. It has nothing really to do with the Subaru brand as it is today.”

Even the standard Impreza is no longer offered here, which Hurtig admits was a strategic decision to allow Subaru to focus on its core values as a crossover and SUV brand. On the other hand, the new BRZ sports car was never an option for any European market.

Overall, though, Hurtig is honest in admitting that no one area of the business is to blame. “I’m not defending [us]. The numbers are insane and ridiculous. There’s not just one thing; it actually boils down very much to our organisation, our aggressiveness, our way of working.

“We’ve changed the management, we’ve changed the team, we’ve changed a lot of things during the second half of 2020. That’s why we’re now starting the recovery scheme.”

It’s a pity, then, that plans to turn over a new leaf in 2021 have already hit a roadblock in the form of the third national lockdown to face England in the last 12 months and similar restrictions in Wales, Scotland and Northern Ireland.

“I have to admit I didn’t expect a lockdown three, to be honest”, said Hurtig. “But it is what it is again. We were due to have the fourth dealer conference to draw up the plans and everything, but we had to postpone it in the morning, because Boris was talking the night before.”

Ambitious targets remain in place, however. Subaru lacked the required online presence in the previous lockdowns and didn’t offer ‘click and deliver’, but that’s now up and running.

“I had a very good rollout plan before the lockdown came; now we have to be more realistic,” said Hurtig. “But we’re still looking for growth: 30% in Q1 is the target. We were looking for far more growth during 2021, but I have to be a bit humble in this situation. However, we can’t just sit and relax and wait for the lockdown to open up.”

New cars in the pipeline are hoped to pick up some of the slack of the sales recovery. These include an updated XV, a facelifted Forester and the new Mk6 Outback off-road estate landing on UK shores in May.

Furthermore, Subaru will detail its first battery-electric car: an SUV, developed as part of a joint venture with Toyota, that will go on sale by 2025.

There are further positives in the fact that Subaru’s volume in Europe is so small that it’s classified as a ‘niche manufacturer’ so avoids the most draconian EU CO2 target. Brexit will also have “not really any” significant effect to the business, according to Hurtig.

While some have already written off Subaru’s long-term chances a new golden age in Europe, Hurtig is optimistic for the future and wants last year to quickly become history.

“2020 was a disaster for us,” he said. “But from our perspective, there’s a good way forward and a good future for us, which we are very much committed to.”
