Subaru Boxer Turbo Diesel (2008 available).

Subaru Diesel for Legacy and Outback

Subaru will be using the Geneva Auto Show to introduce their new boxer diesel engine to Legacy and Outback models. The long awaited engine is a 2.0L that produces 110kW (150 PS)/3600 rpm and has a maximum torque output of 350Nm/1800 rpm. Both models will come with electronic steering in order to maximize fuel efficiency.

The World’s First SUBARU BOXER DIESEL debuts with the Legacy/Outback

Tokyo, February 8, 2008 - Fuji Heavy Industries Ltd. (FHI), the maker of Subaru automobiles, today announced the major features of its Subaru exhibit at the 78th Geneva International Motor Show slated for March in Geneva, Switzerland (Press days: March 4 and 5; Open to the public from March 6 through 16).

Subaru Boxer Diesel: Features

The Subaru Boxer Diesel takes advantage of high rigidity of the horizontally opposed engine. It uses an aluminum-alloy cylinder block. With its engine width equivalent to that of a horizontally opposed petrol engine of the same displacement volume, it is 61.3-mm shorter in length, achieving top-level lightweight and compact design of the class.

Its unique layout allows the right and left pistons to negate each other’s inertia. This translates into smooth rotational balance, low vibration and superior quietness.Furthermore, thanks to excellent accelerator response, and with reduced friction and inertia resulting in smooth acceleration, the Subaru Boxer Diesel features engine characteristics worth the name of a sport diesel.

Subaru Boxer Diesel: Main specifications

Engine type: Horizontally opposed 4-cylinder DOHC 16-valve turbo diesel

вот интересные подробности из анатомии зверя

The engine has a ‘square’ bore and stroke of 86 mm and a compression ratio of 16.3:1. Compared to Subaru’s 2.0-liter gasoline engine fitted to the Impreza, Legacy and Forester, the 2.0-liter Boxer Diesel has a 11 mm longer stroke and 6 mm smaller bore for a capacity of 1,998 cc versus 1,994 cc.

Thanks to a bore pitch shortened from 113 mm to 98.4 mm, the overall engine block length is only 353.5 mm compared to the gasoline version’s already compact 414.8 mm.

The block is of a rigid semi-closed deck design, while all five main bearings in the alloy cylinder block use metal composite supports for added strength and durability. It also enhances refinement, providing a similar thermal expansion to that of the crankshaft.

Extra water-cooling slits have been added between the cylinder bores and the high-strength pistons are squirted with oil to enhance cooling. The large ends of the connecting rods feature an asymmetrical profile for assembly precision and reduced friction.

The high-strength crankshaft has a special surface treatment to withstand the diesel engine’s high combustion pressures while the uprated cylinder heads have roller rocker arms. In addition, the cam-drive is via a chain system that better handles the variations in torque of a diesel engine.

специальная обработка коленвала

The new Boxer Diesel uses an advanced 180 MPa (1,800 bar) common-rail fuel-injection system. Special, short-length solenoid injectors ensure the engine’s width is no greater than that of the 2.0 litre boxer gasoline unit, despite the diesel’s longer piston stroke.

The variable nozzle turbocharger ensures the correct boost throughout the engine’s rev-range and its low center-of gravity position under the engine and close to the catalytic converters increases environmental performance.

Напоминаю, что сегодня открылся Международный Автосалон 2008 в Женеве (Швейцария)
на котором предоставлены новое поколение автомобилей Субару  с "пламенным сердцем" под названием

SUBARU BOXER (TURBO)DIESEL

С которым (надеюсь) будет открыта новая веха в самодельной (и не только) авиации, так как даный мотор по ряду характеристик (максимум мощности при довольно низких оборотах (3600), довольно малый вес и сбалансированность) идеально подходит как основа для конверсии. ;D

Прямой потомок первых опозитников субару которым недавно исполнилось сорок лет !

Пока доступны версии 2литра - 150 коней, но в скором будущем появится несколько форсированная версия длы Субару Импреза (спорт) - 180 коней. 😡


Пока выставка доступна для прессы (4-5 Марта) но с 6го по 16тое Марта будет доступна для публики.

Приглашаю посетить и ознакомится с двигателем, так сказать, "вживую" ! :🙂


Для тех кто не сможет посетить - буду т выставлены фото тут ….а пока материалы из закромов Инета. :-/

С Уважением,
Насос  😎 (Леонид)

сводки с полей

опубликован выступ президента Субару в Женеве (конечно же главной темой был дизель субару 🙂 )


....it was essential for Subaru to develop our own diesel engine. A quality ride for every passenger and environmental protection was embodied by integration with this diesel engine and Subaru unique All-Wheel-Drive. SUBARU BOXER DIESEL. The World’s First Boxer Diesel for Passenger Cars. We have successfully achieved a longer stroke arrangement that generates powerful torque without increasing the overall engine width. The unique horizontal layout achieves smooth rotational balance and results in minimal vibrations and noise, both at idle and high speed. It provides levels of quietness previously unknown to the ordinary diesel users. It offers smooth and outstanding accelerative response, making it a diesel engine with a distinctive sporty feeling. Thanks to its highly rigid design, the boxer diesel is the class-leading lightweight and most compact diesel engine on the market. Last but not least, the Subaru Boxer Diesel achieves excellent environmental performance; it has the best fuel efficiency...
