Nissan also benefited from acquisition of previous manufacturers called Prince Motor Company who manufactured a six cylinder called the Prince G engine, and Tokyu Kogyo Kurogane who helped develop Nissan's current engines. [3] Honda and Mike Hailwood raced in the 1960s with the RC166 250 cc (15 cu in) (0.25 L) six-cylinder, 24-valve motorcycle engine. Straight-six diesel engines with much larger displacements are commonly used for industrial applications. In fact the engine used a variation on the overhead valve layout, with a camshaft mounted in the engine block driving the inlet rocker arms via traditional vertical pushrods. Nissan started with their H-series, and later the L-series (up until 1986) of the early Nissan Z-cars, also known as Fairlady Zs, as well as the RB engine series engines (in the R31-R34 Skyline). Lowe runs a T-4 62-1 Turbonetics turbocharger on his 292ci six and is currently pushing 11 psi and still running the engine on pump gas. GM pickup trucks abandoned the straight-six in 1984 for the 4.3 V6, Ford dropped the straight-six in favour of the Essex V6 in 1996. The last Alfa Romeo model using a straight-six was the 1961-1969 Alfa Romeo 2600 (1961–1969), before the company switched to V6 engines due to their shorter length and the torsional problems experienced in the long crankshafts of the Alfa straight-six engines. In 1971, Leyland Australia replaced the Austin 1800 with the Austin X6 range, marketed as the Austin Tasman and Austin Kimberley. Despite this, straight-six engines became rare in American cars, although they continued to be used in trucks and vans. Mercedes-Benz debuted the OM603 3.0 L (180 cu in) diesel in 1985. Production of Volvo straight-six engines ceased in 2015. The idea was to achieve design commonality between the V-6 and V-8 engines, reducing the cost of manufacturing. Aston Martin used a straight-six for many years, as did Austin-Healey in their Austin-Healey 3000. This is because the six pistons with six unique phases cannot be "paired" as in the four-stroke case. Holden engine sizes included the 138 cu in (2.26 L), 149 cu in (2.44 L), 179 cu in (2.93 L) (1964–1966), 161 cu in (2.64 L), 173 cu in (2.83 L) (1971–1984), 186 cu in (3.05 L) (1968–1971), and 202 cu in (3.31 L) (1971–1986, the largest and most popular of the series). These include various types of heavy equipment, power generation, as well as transit buses or coaches. British sports car company TVR designed its own straight-six, known as the Speed Six, which was also used in a number of models, including the Cerbera, Tuscan, Tamora, T350C/T, Sagaris and the prototype Typhon. Inspired designs on t-shirts, posters, stickers, home decor, and more by independent artists and designers from around the world. It ranged from 3.6 to 4.0 litres, with its largest capacity of 4 L (240 cu in) used in the Tuscan and Sagaris. Introduced in the 1930s, these engines were used with great success in Rover's post war cars (the 'P3', 'P4' and 'P5' models). Non-AMG Mercedes-Benz models will employ a lower-output version of the M256, without the electric supercharger but with the motor/generator and 48-volt systems. The Bristol engine had a distinctive valvegear arrangement.

And the electric A/C compressor can also deliver the car’s cooling needs efficiently while maintaining cold air during extended idle stops. Yuchai makes straight-six diesel engines for automotive, industrial, and marine applications. [18] The result was displayed in the Jaguar XK120 at the London Motor Show in 1948. Size is the major factor that defines Inline 6 vs V6 perfectly. Caterpillar makes straight-six diesel engines for automotive, industrial, and marine applications. Another factor reducing the ability of the large six-cylinder engines to achieve high speed is the simple geometric reality of a relatively long stroke (undersquare) design. Because it is a fully balanced configuration, the straight-six can be scaled up to very large sizes for heavy truck, industrial and marine use, such as the 16 L (980 cu in) Volvo diesel engine and the 15 L Cummins ISX used in heavy vehicles. Virtually every heavy duty over-the-road truck employs an inline-six diesel engine, as well as most medium duty and many light dutydiesel trucks. the now standard 500-cubic-centimeters-per-cylinder displacement, Why 0.5-Liter Cylinders Will Soon Dominate Automotive Engine Design, First Drive: 2019 Mercedes-AMG CLS53 and Mercedes-Benz CLS450, 2019 Mercedes-AMG GT 4-Door: The More-Door AMG. 3. That is, piston #1 mirrors #6, #2 mirrors #5, and #3 mirrors #4, largely eliminating the polar rocking motion that would otherwise result. Up until about 2006, Toyota still offered the FZ-series, G-series, and the JZ-series engines. It featured a durable design with a cast-iron block and cylinder head, hydraulic lifters (with non-adjustable rockers), and seven main bearings. BMW's first product was the 1917 BMW IIIa straight-six aircraft engine. This is even true with the very precise piezo injectors in the M256, which operate at up to 2900 psi of injection pressure. It declined further after the 2005 introduction of the third generation Jeep Grand Cherokee, which also used the 3.7 L (230 cu in) V6. Also in 1967, Honda raced the straight-six 297 cc (18.1 cu in) RC174 in the 350 class, with bore and stroke of 41 mm and 37.5 mm.
