• Usually PT/10gr ft³/PT/20gr ft³ corresponds to the original vehicle size of the emission standard, which is enough to achieve the corresponding emission effect. Since ours is a replacement product, not the original, there is a difference in precious metal content with the original DOC. If you mind this situation, don't pay. |

The Diesel Oxidation Catalyst (DOC) is a device installed inthe engine exhaust line to convert carbon monoxide (CO)and hydrocarbons (HC) in the enginèexhaust into harmlesswater (H20) and carbon dioxide (CO2) through oxidationreactions.
Formula: 2CO+O2--2CO2 CxHy+(x+4y)O2--xCO2+2yH2O |
Fast facts
1.Converts carbon monoxide (CO) into carbon dioxide (CO2) and water
2.Can eliminate muffler requirement
3.Harmful particulates are oxidised into harmless products
What are the strengths of our solution?
Our DOCs provide a simple solution for original equipment manufacturers (OEMs). They’re easy to install and maintain and don’t require any additional control from the machine operator. In many cases, the need for a muffler can be eliminated, and our DOCs can also allow for a wider ratings envelope. Concentrations of NO and NO2 can be optimised in the exhaust stream, and if your engine has SCR, this will make it more efficient and reduce diesel exhaust fluid (DEF) consumption requirements. Using a DOC also enables additional passive regeneration in DPF systems.

Great, New Commentary!
Format: Hardcover
This commentary by Robert Yarbrough will become, I predict, a top-rated volume on the Pastoral Epistles. These epistles are ideal for the style of commentary we find in the Pillar New Testament Commentary (PNTC) series. As respected and valuable as the NICNT volumes by the same publisher are, these Pillar volumes are simply more valuable. They have a better center of focus, are more consistently conservative, and have more value for pastors without sacrificing scholarship. This volume succeeds in reaching that standard too. As you might have guessed, the editorship of D. A. Carson likely keeps this series moored to that lofty perch. BTW, don’t miss the editor’s preface where Carson fawns over Yarbrough’s work here.
I was in love with this commentary within a few pages of its fine Introduction. So many commentators lose their way in the Pastoral Epistles. I have long suspected that it has far more to do with the authors dislike of what these epistles say rather than any actual problem found within them. Yarbrough is not sucked into the irrational fear of using the term “pastoral epistles” as so many are today either. It’s a breath of fresh air.
He opens the Introduction with eight theses on pastoral heritage in these epistles. To my mind, that was a great way to present introductory issues. Next, he does a section each on Father, Son, and Spirit respectively in the Pastoral Epistles (PE). He was particularly perceptive in discussing Paul as a working pastor, even dispensing some silly critical theories along the way. He then tackles in turn geography, people, and key terms. He ends with a section on authorship and other usual introductory matters and masterfully reaches conservative conclusions.
The commentary itself was even better! The phrase “real help” comes to mind. He showed off his skill, for example, in the perpetual battlefield of Titus 2. He gently yet surefootedly takes us where that disliked passage goes. He’s kind to dissenters, careful in scholarship, but not afraid to reach a conclusion. I don’t know about you, but that’s how I like my commentaries. 5 stars all the way!

A Thorough Commentary that Needs Less Neutrality
Format: Kindle
Dr. Yarbrough has addressed the meaning of the Pastoral Epistles with the excellence we have have come to expect from him. However, sometimes he seems reluctant to take a stand on some controversial issues (other than on Pauline authorship and matters of basic Christian orthodoxy, to both of which he is correctly firmly committed). When several possibilities of meaning are possible, for example, it would be helpful to know which hypothesis he favors, and why. While occasionally he does state a definitive opinion, more often he does not, perhaps in a laudable but somewhat overdone effort to avoid controversy with fellow theologians. However, when one reads a 1000+ page commentary written at a scholarly level, one expects the author to give his or her expert opinion on such matters—indeed, it is a major reason that one purchases and studies a commentary. To conclude on a more positive note, Dr. Yarbrough’s observations on Greek word usage, including numerous Old Testament passages from the Septuagint, the Apostolic Fathers and apocryphal works, were very helpful in aiding the reader in understanding fine shades of meaning. His pastoral observations and deductions based on the text are simply excellent. His discussions of the strengths and weaknesses commonly encountered in Christian leaders in Western countries versus those observed in leaders from other nations were fascinating and edifying, not to mention occasionally convicting (in a good way)—even for readers who aren’t pastors, like me.

Unimpressive
Format: Hardcover
Concerning various controversial questions of like Pauline authorship and women in ministry, Yarbrough's commentary is lackluster, polemical, and altogether dismissive of large swaths of evangelical scholarship that run counter to his claims. There are better commentaries from an evangelical perspective (I. Howard Marshall, Philip Towner) that seriously address such questions without resorting to hand-waving. Overall, an unimpressive and polemical work that is superseded by better words.
