news Zetor announces own 4 cylinder TIER 4 final engines, and Deutz cooperation






So what Mr. Kolhammer is explaining is that they continue to build Zetor 4 cylinder engines, yet install an SCR system and an active soot filter, to achieve TIER 4 Final emissions.

Clearly, because of the parallel introduction of their own TIER 4 Final 4 cylinder engine, this means that this cooperation with Deutz does NOT mean the end of the Zetor 4 cylinder engine, unlike some newspapers write. (!?!)

And the Deutz press release:


So what Deutz is saying is that they are going to sell TCD 2.9 and TCD 6.1 engines to Zetor, to be implemented into production during 2015/16.
According to what factory spokesmen have said informally to forum user Forterra11441, it involves the new Major (which means it will get the TCD 2.9) and new six cylinder ranges which will get the TCD 6.1

In spite of all, i take my hat off for Zetor R&D for what they have done in the past few years, competing against competitiors nearly 10 times as big..

These continuous refinements on Zetor engines:

the VERMI system is used on the Forterra 150HD for better throttle response and more efficient use of the DPF. However what Zetor engines need is a flatter torque curve under 1400rpm, which the CR system is able to provide in the future.

The annual report of Motorpal reveals that the 2000 bar version of the CR system will not be commercially available before 2017, as well as that Motorpal sells components to Deutz for use on China made Deutz engines, and that Motorpal already produces Common Rail injectors for third parties.

Also, an R&D subsidy is granted for the project till 2017

The goal is to meet the yet-to-be-implemented TIER 5 emissions in which not only grammes per KwH is legislated, but also the total particle count: Which means that JCB, Sisu and FPT have to fit a soot filter anyhow, despite their best efforts to avoid the awkward DPF... In fact, the environmental agency discovered that manufacturers like JCB, Sisu and FPT met the grammes per KwH by using up to 5 injections per cylinder stroke, however this emits a much bigger number, of smaller particles. Therefor the new legislation is proposed by EU and will allmost certainly be implemented in order to limit the amount of individual particles.
 
The current stage of Motorpal common rail system is already being tested on MTZ ( Belarus) tractors:

However the MTZ website says they currently use Bosch CR and SCR systems ??

What will Zetor use for TIER 4 final ?? Most likely also the CR system because the ECU has the ability to control the SCR system
 
I think that MMZ (MINSK MOTOR PLANT) is searching cheaper solutions.

They used Motorpal pumps and CZ turbos for a long time, but Motorpal cannot offer an integrated SCR solution, which Bosch can. If you read what Motorpal is up to, they want to offer a single solution (injection and aftertreatment) too, eventually.

Still surprising how MTZ meets TIER 3B with no soot filter and 2 valve technology..
