US truck and bus manufacturer Navistar is planning to launch its new In-Cylinder Technology Plus (ICT+), which will comply with 2010 US Environmental Protection Agency (EPA) emissions regulations.

The new engine technology combines the company's In-cylinder engine expertise with urea-based after-treatment.

Navistar said that the current move is in response to a recent court ruling, according to which, the company could not continue paying fines for selling its engines which are incompatible with environmental standards.

According to the company, the new In-Cylinder Technology Plus will be available during early 2013 and will also offer it in production-ready vehicles by the same time.

Navistar chairman, president and CEO Daniel Ustian said the company has shared its new technology path with the EPA and California Air Resources Board (CARB), and both agencies are encouraged by its plans.

"We will continue to work with the agencies to ensure that our customers receive uninterrupted deliveries in all 50 states during this transition," Ustian said.

The company is planning to continue producing and transporting current model EPA-compliant trucks in all vehicle classes through suitable blend of earned emissions credits and/or non-compliance penalties (NCPs) during the conversion to ICT+.

The new technology will also position the company to meet greenhouse gas (GHG) rules in advance of 2014 and 2017 requirements.
