HORSE Advances Auto Innovation with New Turbo Flex Engine Production in Brazil
HORSE, a global leader in innovative, low-emission powertrain systems, is set to expand its production in Brazil with its powerful and efficient 1.3-litre Turbo Flex Fuel engine. This decision follows the successful introduction of the 1.0-litre models earlier this year. With proven performance in the Brazilian market, HORSE will commence local production at its Curitiba plant by 2024.
These advanced engines are designed to meet the specific needs of the South American market, offering exceptional power, torque, efficiency, and emissions standards. Capable of running on both gasoline and sustainable ethanol, these Turbo Flex engines comply with Proconve L7 regulations, equivalent to Euro6d, and are in the process of certification for the forthcoming L8 standards.
The 1.0-litre three-cylinder 'HR10' engine delivers a peak power of 125PS (92kW) and a maximum torque of 220Nm, with 90% accessible from just 1,750rpm. This ensures unmatched throttle response under all driving conditions.
The 1.3-litre four-cylinder 'HR13' engine offers a peak power of 170PS (125kW) and a maximum torque of 270Nm from only 1,600rpm.
Over 170,000 hours have been invested in developing the 1.0-litre Turbo Flex engine to satisfy the stringent demands of South American consumers. The Curitiba facility, equipped with state-of-the-art technology, will have an annual production capacity of 500,000 engines.
Following an investment of R$100 million in the Curitiba plant, production of the HR13 will start in 2024, alongside the HR10.
Guillaume Tuffier, Director of Powertrain Strategy & Advanced Engineering at HORSE Powertrain Solutions, stated, "We are committed to delivering tailor-made powertrain solutions globally. Producing the HR10 and HR13 in Brazil leverages local expertise to meet regional demands. These engines offer superior driving dynamics, dual-fuel capability, and unmatched quality, making them perfectly suited for the Brazilian market."
HR10 and HR13 engines incorporate a Diamond-Like Carbon (DLC) coating on critical moving parts, reducing friction and boosting fuel efficiency. The lightweight aluminium blocks feature Bore Spray Coating (BSC) for quicker engine warm-ups, lowering emissions and fuel consumption by 1%.
Additional features include a friction-reducing polymer surface treatment on crankshaft components and a Reflex-equipped Start & Stop system for enhanced efficiency.
Thanks to an innovative delta-shaped cylinder head, these engines are compact, lightweight, and have a lower centre of gravity than competitors. The integrated exhaust manifold enhances turbo response and low-speed torque. Both engines use an electronic wastegate for precise turbocharger control, achieving optimal boost pressures.
Continuously variable exhaust valve timing, enabled by an electronically-actuated double-valve control shaft, improves combustion efficiency and performance. Roller bearings in the controller minimize friction, further enhancing efficiency.
Both engines also benefit from a bespoke direct injection system designed specifically for ethanol, featuring centrally-mounted six-hole injectors that operate at 200, ensuring optimal fuel atomization and efficient power delivery without sacrificing fuel economy.
