GT Technologies supplies valvetrain components on Ford's New 6.7L Diesel Engine
Ford has introduced a new in house Ford designed diesel engine to replace its former long term diesel engine supplier, Navistar. The 2011 edition of the Ford Super Duty pickup will get an all-new 6.7L V8 diesel named Scorpion.
The valvetrain features dual hydraulic lash adjustors (two hydraulic lash adjusters contained into a single roller tappet body) manufactured and assembled by GT Technologies. Improved performance is achieved and valvetrain reliability is optimized by using two pushrods per cylinder instead of the conventional single pushrod, augmented by individual rocker arms assembled onto a fulcrum plate. This rocker arm/fulcrum assembly is also manufactured and assembled by GT Technologies.
Parts supplied by GT Technologies into these two critical engine components are from the following respective plants are:
- Toledo, Ohio facility
- Stamped rocker arms
- Defiance, Ohio facility
- Roller Bearing assembly for the dual tappet
- Tallahassee, Florida facility
- Lash adjusters for the dual roller tappet
- Assembly of the dual roller tappet
- Assembly of the rocker arms/fulcrum assembly
This new 6.7-liter Power Stroke will be fully compatible with B20 biodiesel blends, addressing one of the issues current Power Stroke operators have had with the old Navistar engine. Because the current engine injects some fuel into the exhaust stream for particulate filter regeneration, the use of B20 has caused damage to those engines. This will no longer be true for this new Ford designed engine.
Production volumes will commence in February, 2010.
GT Technologies starts production on Ford’s V8 6.2L Boss Engine
Beginning March 2010, Ford Motor Company will be launching a new engine to replace a portion of its fleet of modular designed V8s. This new V8 is called the 6.2L Boss and GT Technologies will be a key supplier of valvetrain components for this engine. Products currently being supplied for production application by GT Technologies for this newly designed Single Overhead Cam, 16 valve engine will consist of:
- Manufacture of Roller Bearing Assemblies from GT Technologies’ Defiance, Ohio facility for the cast steel rocker arms.
- Manufacture of Hydraulic Lash Adjusters (HLA) and the assembly of these HLAs into the cast steel rocker arms will be done at GT Technologies’ Tallahassee, Florida facility. Final assembly of the rocker arms and rocker shaft will also be provided out of our Tallahassee facility with final shipment to Ford’s engine plant.
Production of this engine is to be done at Ford’s Romeo Engine Plant in Romeo, Michigan and is destined for the new 2011 Ford F series pickup trucks as an option engine.
GT Technologies begins production on FPT Brazil Rocker Arms
GT Technologies has been selected to supply the Intake & Exhaust Rocker Arms for the FPT Engine manufactured in Campo Largo Brazil started production in November 2009. These components will be used in 1.6L & 1.8L 16V flexfuel (gasoline and Alcohol) and pure gasoline engine for passenger car and light commercial.
Rocker arms production will be manufactured by GT Technologies do Brazil located in the Industrial Center of Curitiba City, 32 km from FPT Engine Plant.
GT Technologies partners with major OEM to Engineer New Variable Actuation System
GT Technologies has been selected to engineer and develop an electro-mechanical variable actuation, which will yield improvements in performance, emissions and fuel economy. The partnership agreement is a 18 month development project. The deactivating system is electro-mechanical and represents the state of the art in development. The selection for this project is indicative of GT Technologies capability to engineer valvetrain components and systems to achieve functional requirements and feasible manufacturing.
