Paperback. Upcoming automotive regulations require near-zero emissions, making cold-start catalyst heating a key challenge. This work investigates post oxidation through secondary air injection into the exhaust manifold to oxidise unburned fuel from rich combustion, generating heat and accelerating catalyst warm-up. The study combines experimental tests on a turbocharged four-cylinder engine with 3D-CFD simulations. A constant flow SAI system was installed near the exhaust valves, achieving stoichiometric conditions before the catalyst and increasing exhaust temperature during cold start due to oxidation reactions. Two numerical approaches were employed: a full engine simulation using the 3D-CFD tool QuickSim to extract detailed boundary conditions, and a detailed exhaust manifold model in StarCCM+ using these conditions to resolve mixing and chemical reactions. Results show that secondary air injection effectively increases exhaust temperatures upstream of the catalyst, and optimisation strategies such as higher air temperature, modified manifold design, and fuel post-injection can further improve post-oxidation efficiency. A constant flow SAI system was installed near the exhaust valves, achieving stoichiometric conditions before the catalyst and increasing exhaust temperature during cold start due to oxidation reactions. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.…

Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.
The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.
To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.
You shall send back the goods or hand them over to Grand Eagle Retail, Bensenville, Illinois, U.S.A., without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods.
