Carrier Supra truck refrigeration engines provide options for CARB compliance

Carrier is also said it offers a simple engine-swap solution to comply with California Air Resources Board (CARB) requirements for diesel truck refrigeration units. “It’s completely backward compatible,” said David Dunn, product manager – Truck Products. “A new Tier 4 engine can fit into any corresponding older model Supra – Tier 2, Tier 1 or older – without any special modifications. It’s a direct swap.”

The Tier 4 requirement, which took effect for 2008 model-year engines, reduces particulate matter output by 50 percent – down to 0.4 grams per kilowatt-hour (g/kW-h) –compared to the previous standard. The engines used on Supra units reduce the output an additional 40 percent. Depending on the model, they also reduce emissions of combined nitrogen oxides (NOx) and hydrocarbons by 12 to 17 percent below the Tier 4 requirement. Tier 4 engines are now standard issue for the Supra 550, 650, 750, 850 and 950, as well as Genesis R-90 units.

“As part of our ongoing commitment to the environment and helping our customers achieve their compliance goals, we’re pleased to offer this enhanced line-up,” said Dunn.

For trucks driven in California, the Tier 4 units comply with applicable CARB requirements. Additionally, for model year 2001 and older Supra units used in California that need to be “emission enhanced” for compliance with CARB this year, the Tier 4 engines can be used as replacements for older engines.

Supra units with the electric standby option can be plugged into an electrical supply at loading docks equipped with power drops, providing yet another compliance strategy, with proper CARB documentation. Using the standby mode, engines can be shut down when parked, eliminating emissions, noise and fuel consumption.

“Whether operating in California or elsewhere, the Supra line provides advantages for Carrier customers seeking green solutions,” Dunn said.
