Isuzu Powers Essential Industries with Legacy and Innovation

With over 30 years of leadership in the Australian truck market, Isuzu’s reputation for reliability continues to resonate strongly with Australian operators. The brand’s legacy of dependability is built on a foundation of high-quality products and exceptional aftersales support, which remains unmatched in the country.

This same commitment to performance and dependability extends to Isuzu’s Power Solutions range, with its off-highway products gaining a dedicated following, similar to their on-road truck counterparts.

Sustained Growth in the Off-Highway Market

Troy Lawson, National Sales Manager for Isuzu Power Solutions (IPS), highlighted that Australia’s off-highway engine market is steadily growing and is expected to continue this trend.

"According to recent data from the Department of Climate Change, Energy, the Environment and Water, the non-road diesel market is projected to reach 750,000 units by 2028 and is forecast to hit approximately 945,000 units by 2043," Lawson explained.

He continued, “This sector is currently expanding with power solutions deployed across agriculture, marine, mining, facilities management, and emergency services. These power plants power critical machines like tractors, cranes, loaders, excavators, bulldozers, barges, pumps, and generators, all of which are essential to keeping industries running—downtime is simply not an option.”

As Australia doesn’t manufacture off-highway engines, most units are imported from China, Europe, and the United States. However, Lawson emphasized the superiority of Isuzu’s offering.

Built in Japan for Australian Conditions

“As the report highlights, there’s a variety of imported products available in Australia, but not all are ideally suited to our environmental and operational conditions,” Lawson said. “One of the advantages of our truck DNA here at IPS is that our common-rail engines are designed, engineered, and manufactured in Japan, to some of the highest standards globally.”

He added, “While there are cheaper, less reliable alternatives on the market, Australian industries are increasingly recognising the value of a power solution that is genuinely fit-for-purpose. With Isuzu’s over 100 years of engine-building expertise, we offer improved fuel efficiency, reduced exhaust emissions, lower noise, and unparalleled reliability. Our customers realise that when you invest in an Isuzu product, you pay once, and you don’t look back.”

Engine Options for Diverse Applications

The IPS range includes both four- and six-cylinder Isuzu engines, offering flexibility for a wide array of applications. The 4JJ1 engine is a direct-injection, turbocharged engine with a maximum rated output of 61 kW (81.8 hp) at 2,500 rpm. It’s a popular choice across various industries.

A more powerful variant, the turbocharged 4JJ1-X, delivers 95 kW (127 hp) at 2,500 rpm. It’s available in both Starter and Premium configurations, offering upgraded cooling and control systems, along with a residential-grade exhaust system.

For larger applications, Isuzu’s 4HK1 engine, with a maximum output of 147 kW (197.1 hp) at 2,100 rpm, is a favourite for off-highway machinery. The 4HK1’s common rail direct injection fuel system ensures reliability, low noise, low fuel consumption, and minimal maintenance.

High-Powered Six-Cylinder Options

The IPS range of low-emission, common rail six-cylinder engines caters to industries such as civil construction, mining, and other heavy-duty sectors. The 6HK1 engine, a turbocharged mechanical direct injection model, offers 212 kW (284 hp) at 2,000 rpm and is available in both Starter and Premium configurations.

For larger applications, the 6UZ1 engine provides 270 kW (367 hp) at 1,950 rpm, and the 6WG1 variant delivers an impressive 397 kW (540 hp) at 1,800 rpm. These engines are equipped with premium Australian-designed fitments to ensure optimal performance in local conditions.

Unmatched Aftersales Support

Isuzu’s commitment to exceptional aftersales service extends across its Power Solutions range. With a network of over 70 locations throughout Australia and New Zealand, the IPS range is supported by the same trusted Isuzu team that operators know and rely on for their truck needs.

“We’re proud to back our products with a comprehensive support network that ensures businesses across the country can keep running smoothly,” Lawson said. “Isuzu pioneered Japan’s first air-cooled diesel engine in 1936, and we’ve continued producing over a million units annually ever since. Our engines are not only reliable, but they offer efficiencies that make a real difference.”

He concluded, “Our team of specialists and engineers work closely with industries to deliver tailored solutions for any challenge, ensuring that Isuzu Power Solutions products continue to drive essential industries forward.”
