An AI sales agent's DEUTZ TCD engine order, checked before it goes out

An AI sales agent prepares an engine order for a machine builder: a DEUTZ TCD series, a power rating, the market and emission stage, exhaust aftertreatment, options such as the flat version and HVO fuel, the quantity, and the engine weight and torque it states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the DEUTZ datasheet figures plus ordering rules modeled from comparable engine programs, and returns a verdict, every reason and the figures it computed.

Scope: DEUTZ TCD engines only (TCD 2.9, 3.6, 4.1, 6.1, 7.8, 12.0 V6, 13.5 and 16.0): power range, emission stage, aftertreatment, flat version, HVO, weight and torque. See everything this validator covers

This validator models orders for the DEUTZ TCD industrial and agricultural engine series, not just the scenarios shown below.

  • Series and rating — eight series with the power range, maximum torque and weight each DEUTZ datasheet publishes (for example TCD 7.8: 160 to 260 kW, 1,400 Nm, 725 kg; TCD 16.0: 350 to 520 kW, 2,890 Nm, 1,260 kg). A rating outside the series range is blocked.
  • Emission stage and aftertreatment — EU Stage V and US Tier 4 final versions, the emission-downgrade version (Stage IIIA / Tier 3, without aftertreatment) that the datasheets list for agricultural and generator set use, and the aftertreatment each needs. Which series have a downgrade version, a flat compact version (TCD 12.0 V6 and TCD 16.0) or listed HVO fuel readiness follows the datasheets.
  • Machine fit and stated figures — the engine weight against what the machine allows, and the engine weight and maximum torque the order states, which must equal the datasheet figures.
  • Ordering rules (modeled) — that the EU market needs Stage V and the US market needs Tier 4 final, that Stage V needs DOC/DPF and SCR and Tier 4 final at least SCR, that the downgrade version is for agricultural and generator use and ships without aftertreatment, and the 1,000-engine volume threshold that goes to a person.

Any TCD engine order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (DEUTZ does not publish list prices, so this page shows no price build-up), other DEUTZ engine families, gas and electric drives, option lists beyond those named, and delivery or service terms. The ordering rules above (market and stage, aftertreatment pairing, downgrade use, the volume threshold) are modeled from comparable off-highway engine programs; they are not DEUTZ-published rules.

The AI sales agentBuilds the engine order from the conversation and says it is ready.
Predictika validatorChecks every rule at once and returns the verdict, each finding, and the computed figures.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Series data that differs by engine (range, torque, weight, downgrade, flat, HVO)Only with workarounds
Eight series each have their own range, weight and feature list. A rules-based CPQ needs a compatibility table or one rule per series, and every datasheet update means editing them.		The series arrives in the request and its published figures are looked up and checked on every call.
Market, emission stage and aftertreatment togetherOnly with care
Three choices constrain each other (the EU needs Stage V, Stage V needs the full aftertreatment, the downgrade version ships without). It can be built, but each new pairing is another rule to maintain.		The market, stage and aftertreatment are checked together, in any order the choices arrive.
Stated weight and torqueOnly with care
The stated figures come from the chosen series, so a rule has to look them up and compare.		The stated weight and torque are fields in the request, compared with the datasheet figures on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved or a step is completed, so a person often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1A rating of 265 kW is outside the 160 to 260 kW range of this engine series.
2A rating of 150 kW is outside the 160 to 260 kW range of this engine series.
3Engines sold into the EU market must be EU Stage V; the order has a different emission stage.
4Engines sold into the US market must be US Tier 4 final; the order has a different emission stage.
5Stage V needs the full aftertreatment (DOC/DPF and SCR).
6Tier 4 final needs at least an SCR aftertreatment system.
7The emission-downgrade version is offered for agricultural and generator set (EDG) use, not for mobile machinery.
8The datasheet lists no emission-downgrade version (Stage IIIA / Tier 3, without exhaust aftertreatment) for this series.
9The emission-downgrade version is delivered without exhaust aftertreatment; the order lists an aftertreatment system.
10The datasheet lists a flat compact version only for the TCD 12.0 V6 and the TCD 16.0.
11The engine weighs 725 kg; the machine allows 700 kg.

13The order states a maximum torque of 1,500 Nm; the series gives 1,400 Nm.
14The datasheet does not list HVO fuel for this series; a person should confirm the engineering release.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an engine order for a machine builder: a DEUTZ TCD series, a power rating, the market and emission stage, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the DEUTZ datasheet figures plus ordering rules modeled from comparable engine programs, and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 1,200 DEUTZ TCD 13.5 engines at 440 kW for mobile machinery, sold into the US, as US Tier 4 final with SCR aftertreatment only. The machine allows an engine weight of 1,000 kg. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings and two approvals, all in one answer. The datasheet lists a flat compact version only for the TCD 12.0 V6 and the TCD 16.0. The engine weighs 1,012 kg; the machine allows 1,000 kg.
    6. 
      
  6. The validator returned two blocking findings and two approvals in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for series data that differs by engine (range, torque, weight, downgrade, flat, HVO), a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the engine series to DEUTZ TCD 12.0 V6 and the rating to 380 kW. It sets the stated engine weight as to 995 kg and the stated maximum torque as to 2,130 Nm.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Not blocked, but held for a person.
    12. 
      
  12. The two blocking findings are cleared; one approval remains for a person: large volume order.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the engines to 800.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Four problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
