New heavy-duty engine for Hino 500 Series

Improved performance and operational efficiency, along with reduced emissions are hallmarks of the all-new A05 five-litre four-cylinder engine powering the newly launched Hino 500 Series Standard Cab range.

The A05 is a derivative of the larger A09 six-cylinder engine fitted to the 700 Series heavy-duty models in Japan and the heavy-duty 500 Series Wide Cab models in Australia. The A05 has the same dimensions in terms of cylinder bore and crankshaft journal diameters as its ‘big brother,’ the A09.

“A variant of the A09 also powers the Hino Dakar Rally team’s “Little Monster’’ race truck,” said Daniel Petrovski, Hino Australia Manager Product Strategy.
 
The new A05 engine has three power ratings which are dependent on the model selected – the FC 1124 and FD 1124 models feature the A05-TE engine, which delivers 240hp at 2300rpm and 794Nm of torque at 1,400rpm.

FE 1424 crew models have the A05-TD with 240hp at 2300rpm and 833Nm at 1,400rpm.

“The range-topping FD 1126 and FE 1426 models sport the top performing A05C-TC, which produces peak power of 260hp at 2300rpm and a very healthy torque rating of 882Nm at 1400rpm," said Petrovski.

“The high torque output and low revving nature of this engine are further evidence of its heavy-duty genes,” said Petrovski. “While reducing rpm improves the fuel efficiency it also reduces stress on the engine and ultimately improves reliability and durability,” he said.

“The new A05 engine produces as much torque as the larger J08 engine in the 500 Series Wide Cab models, and has 10 to 20 per cent more torque than the J07 engine in the outgoing Standard Cab vehicles."

Auxiliary braking has also taken a big step forward thanks to a new engine brake.

“Better known as a Jacobs Engine Brake® or Jake brake, the new 500 Series will be the first Japanese medium-duty truck below 15 tonne Gross Vehicle Mass in Australia fitted with a true engine brake,” Petrovski said.

“Combined with a traditional exhaust brake, the downhill descent control is class leading,” he said. 

“The A05 can also be specified with a 343Nm live-drive power take-off (PTO) driven at engine speed. Suitable for all types of applications requiring engine dependant drive, it is sure to make its mark in applications such as mixers and vacuum trucks.”

On the transmission front, the new range comes with either manual, automated manual (AMT) or torque converter automatic.

For drivers who prefer to use a clutch pedal and shift gears themselves, the Hino LX06 and MX06 six-speed manual gearboxes are fitted as standard to the FC and FD models, while the FE is fitted with the new MX07 seven-speed manual, which offers more operational versatility and one more gear than its rivals.

“The LX transmission is proven in the outgoing 500 Series Standard Cab and we have added the new range of MX transmissions to support the increased torque of the A05 engine,” said Petrovski.

FD and FE customers also have the option of an AMT in MX06 and MX07 – six- and seven-speed respectively –   guises.

With these versions a unique rotary dial on the dash is used to select reverse, neutral and drive while a lever on the steering column lets the driver switch between auto and manual mode and manually select gears.

“In addition, a six-speed Allison 2500 Series automatic transmission is available across the range of 500 Series Standard Cabs,” said Petrovski. 

“This means Hino is the only Japanese manufacturer to offer an automatic transmission in all models from the car licence 300 Series through to the 6x4 FM 2632.”

Hino says new 500 Series Standard Cab the cleanest ever

Trade Trucks AU  /  November 22, 2018

Hino is claiming that its new 500 Series Standard Cab will have the cleanest exhaust emissions of any Japanese-built medium duty truck in Australia, equivalent to Euro 6, when it is launched towards the end of November.

Hino believes this is a significant step forward on exhaust emissions in this class of truck. It adds that all models within the new Hino 500 Series Standard Cab range will comply with Japan’s stringent post-Post New Long Term (pPNLT) exhaust emissions standard, which is comparable to Euro 6.

Daniel Petrovski, Hino Australia’s manager of product strategy says there’s an understandable global push for ever-cleaner trucks.

"In Australia we have many customers who have their own environmental impact reduction targets, so by complying with pPNLT early, our new product range is ahead of the game providing a significant advantage for these customers.

"While discussions regarding the introduction of the next exhaust gas emission regulations by the Australian Government are ongoing and the timeline uncertain, it is expected that the European (Euro 6) or Japanese (pPNLT) emissions standards will be two of the acceptable solutions," Petrovski says.

"With the all-new 500 Series Standard Cab, Hino Australia will comply with the expected new Australian emissions regulations, years ahead of their introduction."

The exhaust gas after-treatment unit in the new Hino 500 Series Standard Cab contains a Selective Catalytic Reduction (SCR) system and Diesel Particulate Reduction (DPR) system.

"These two proven exhaust emissions solutions have been used by Hino in the Australian market since 2011 in thousands of vehicles," Petrovski explains.

The exhaust gasses enter the SCR system first, where this system converts oxides of nitrogen (NOx) into nitrogen and water through a chemical reaction with a reducing agent (urea) that is absorbed into a catalyst.

"The new model uses a very small percentage of AdBlue, with the AdBlue tank requiring to be refilled approximately one time for every three diesel tank refuels.

When compared to the current model, Hino expects fuel consumption savings on the new model to be greater than the AdBlue consumption in many applications.

"The current cost per litre of Adblue at service station pumps of approximately $1 per litre is significantly less than the cost per litre of diesel, which further helps SCR make a positive impact on our customers’ environmental and financial targets," Petrovski says.

The DPR component of the exhaust after treatment comes after the SCR and as with the previous 500 Series Standard Cab, the DPR captures the unburnt Particulate Matter (PM) within the DPR filter.

The DPR filter accumulates PM and actively regenerates to clean the filter.

"When compared with our current Hino 500 Series Standard Cab model range, the all-new 500 Standard Cab range will have improved performance, improved fuel efficiency, improved drivability, and the cleanest exhaust emissions of any Hino truck yet," Petrovski says.

Bob, I fully expect to see the 5.1-litre 4-cylinder A05 here. It replaces the 6.4-litre 5-cylinder J07.

The A05 follows the trend in the segment from 6- to 4-cylinder powerplants (that the China market started) on the heels of the Isuzu 5.2-litre 4HK1-TC and 5.1-litre Detroit Diesel DD5 (aka. Mercedes-Benz OM934).
